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.
actually I dont want that high of quality but yes I do know what tools you can use to make them, and you could use blender and gimp for most of it. In the sculpting area blender might not quite be enough for efficient use, so zbrush/mudbox might be required but even then, you don't always need normal mapped models to sell them. i'd focus on diffuse maps only for the moment since your normal map currently doesnt do much for the model. As far as being mean, Im not saying its garbage. I just dont think its something most people would pay for.
@Nitro- Although I don't claim to be great, I do think I have advanced a little farther than that, and figured a little advice might be helpful for him. Granted I think I could have been a little more detailed with my reply but I was in a hurry when I posted it.
as far as the actual advice goes: He looks a bit blocky, and the normal map isnt doing much. He needs to be lower poly or more details. Right now the polys are not all affecting the sillouhette in a way that the difference can be recognized, and goal of this is to have the least amount of polygons with the most detail, being deformed in the easiest way possible. A tough goal but something worth working towards.
