looks nice at first sight, but when you start too look at the model you start to notice a lot of bumps, most of them are because of the way it was modeled, you have to always try to get squares and triangles, not n-gons, that's what makes the bumps most of the time, i really don't know what kind of modeling technique are you using, but for game modeling i'd say study a bit of poly modeling, or even box modeling, seeing the wires you posted i think oyu are using splines, right?
this is how i would have modeled that rim, kinda, i made the drawing in paint
