I don't think its as astonishing as most people here think, but it certainly looks good! Due to the fact that you requested to be "nailed down" and that you already got lots of positive feedback, I'll just give you critics

. I'm aware that some of the following stuff is subjective, so ignore if if you must.
I understand that shaders are all the rage now, so of course you had to use bloom here. Personally, I'm not such a big fan of it, but these are things that you have to see in motion. Right now, I'm just worried that its so "bloomy" that I'll get dizzy when I play it. Don't laugh, I'm a sensible guy, pal!
Even though I'm the minority here, I think that the background is too bright. The bloomshader certainly doesn't help!
I am aware that sometimes, there are pretty bright spots you can - wait for it - spot on nebulas, but are you sure you didn't overdo it? I just went into paint, pasted your last screenshot in there and used the "fill"-tool on the middle of the nebula. This is what I got:

So everything thats pink now was (almost) completely white - a bit much, don't ya think? Maybe tone it down a little. If I were you, I'd try to decrease the contrast by just a little on that "reddish" nebula. Also, is the whole background that colorful or do you only have a few selected spots (=nebulas)? The last spacesim I played was Freelancer, so I'm sorry I'm not
up to date, but I liked what I saw there: well distributed colors, with a few selected spots that had "highlights" in them. Well, whatever.
The biggest flaw - the clearly visible border - was brought up enough times already, so I won't bother mentioning it again!
What I really, REALLY don't like is the ship. What kind of ship is that? I wouldn't want to fly in that ship. I wouldn't feel safe at all. Call me crazy, but why are there only a few metallic "bars"? I assume that the rest must be glass or something, but that much? It kind of destroys the sci-fi, overly-technical mood you've got there.
And then... it's so boring! I'm sorry, but... there is nothing exciting for me to see! It's just... grey. There is no structure, only a shadow and OMGSHADER. Please, do me a favor and make it more exciting. I want to see flying text all over the place and wireframes and beeps and everything else everyone thought was futuristic back in the eighties

(Not really - but please add some more details and make it look a bit more "cool")
Although I'm not a modeller, I'm also not so sure on the distribution of polygons. As far as details go, well, there are two... things, which I assume to be screens (in bright blue, no less) and two handles and thats all that looks detailful to me. Whats with the two grey bars right in the middle up to the very top? I'm aware that this makes it look extremely technical, but I'm sure I would get tired of them pretty quickly, especially because they just look dull and block so much of my view! I don't care if its realistic or not, I want to see what I shoot up (because, I'm sure, thats what I'll do in your game. Right?). Grey and then theres nothing to it.
I like the particles that seem to fly towards you. Makes you think like you really move.

The asteroids look good, although a bit of variation wouldn't hurt. But whats with the ... other things that fly around? The... uh... what it is? A barrel? The round thing. The one that might look like a "U" from the side. Or maybe more a "c". I don't know what it is. Sorry. No clue. I know what you'll say, though! It's space junk! And thus, it can look like a metallic U! Okay, then. I hope you'll add more variation the the spacejunk!
And what is that other thing? A spacestation? It's parts are too small for that - where would everyone go? It also is dangerously close to asteroids. If I were on board on a spacestation with A MILLION ASTEROIDS right next to me (without the spacestation shooting them, no less), I'd leave pretty quickly!
... Maybe it was a prototype for a lightsaber...
So my final guess is that its some kind of checkpoint. To make sure you won't get lost in the asteroidfield. In the final game, you might consider adding a stylish HUD that could explain these things to me, so that I never have to guess again where exactly that metallic "U" might be from, almost as big as spaceships, no less, which all don't seem to have any round part at all, aside from their screens.
I can't say much about the coding, but it seems that one is ROTATING ALL THE TIME. I can see the spacestation in at least four completely different orientations. Thats cool for us "LOLELITE" players, but don't forget the people that want to try something new for a change and try your game out. These people have a hard enough time to control anything in a 3d-environment, they won't have too much fun when they lose orientation all the time. I guess I also would lose orientation sooner or later. In Freelancer, they'd put you in your "normal orientation" after a while. Consider adding something like this!

Too bad theres no story yet. I'd have loved to take a look

. And now you have to create a story with metallic space junk that looks like "U"s! ... Or maybe not

So... all in all, thats quite a good start! But it still seems to miss many important things: Gameplay, for example.

Or is that game all about flying in an asteroid-field? Show me an intense spacebattle! Make a story! Right now, it screams prototype (even though theres no gameplay, so its only a prototype for part of your game), but theres nothing wrong with that.
Don't hate me for this - I sometimes exaggerated a little. It's all in the name of fun (mine, at least

). Plus, you two are "professional" (a term that I'm slowly starting to hate) enough for it. So then, I hope it helps and I look forward to see more of this soon. Even though sometimes my post might paint a different picture
