The quality is a good start but could indeed be improved. I would start with the texture. It looks like painted with very soft brushes. The result looks blurry. I would make more details to create a sharper look. Paint the details in higher resolutions. You can later copy them into the main texture.
...what do you want a Gears of Wars model? may be Assasins Creed? do you at least know the cost of the tools to make such models? do you know the cost of that models? yes, you dont have an idea.
Hm, this is interesting. You said you use Silo, Photoshop and 3ds Max. If I buy this in Germany then I have to spend more than 6,000 Euros, probably something between 7 and 8 thousand Dollars. I don't call this a cheap pipeline.
You can indeed create the same or even better models with less costs. Let us consider Blender. You could do the modeling and sculpting job and even animating for free. You can use TheGimp for free. It competes easily with Photoshop in every category.
If you want to spend money then you can get Lightwave, ZBrush and a 2D painting software way below 2,000 bucks. And you can also create Gears-of-War details.
This is not a matter of money, it is passion, dedication, experience, ambition and of course time, lots of time for learning and some time for creating this content.
