the Idea of an oversized is great!
some criticism:
the desk texture seems too repetitive,
you could try to fix that by using a bigger wood texture,
and by covering it with details:

keyboard
mouse mat
paper, with some doodles on it, or a text
books
post-its
pencils, pens!

a desk may need a chair,
you could use a skybox to show the room.
maybe you could add a computer.
I hope you can make it a great level

It needs to look BIGGER....
And... MADDER... or MEANER...
Like it's going to eat you !!!! Ahhhhhhhhhhh
It dosn't look "Oversized"
It needs something to set the scale...
How about eyes and a mouth on the desk???
Or... How about a very small person???
Or some very small coins and dollar bills...
Something to make the desk look BIG...
Ever see... "Honey I shrunk the kids." ???
But that's just my thinking anyways...

Sorry guys, i took a HUGE break for the Holiday's, i will be getting this level into gear pretty soon, right now i'm making more models to put on the desk such as, papers, manilla envelope, and a paper tray. I will be taking all of those erasers out and am going to try to make it look like a real desk.

Ahhhhhhhhhhhhhhhhhhh...

Can't wait to see...

okay, Here are some in game pics i have.

tell me what you think.

Now... There we go....
It's lookin "Oversized"...
The huge Sharpie is cool!
How 'bout addin' some lighting and shadows...
And... Maybe a big (little) spider to scare people...

Huge improvement!
I actually like te fourh screen,
as it seems to have the most detail.
have you actually planned the desktop, or just.... thrown in some desktop models?
As Terrasame already said: shadows!
but that could be something easy to add later.
I think that when later, when you have some better textures, it will also look better.
It might be just me, but I still don't get what those purple things are...
...what about an aquarium?

Okay, glad you guys like it. I had partially planned the desktop, then i revamped it and thought of a bunch of models to make and add in.
Oh those purples things, are Erasers!!. lol

Maybe it serves as inspiration:
