Hi, Could anyone help me.

I only did Low-Poly things so far, and this is my first High-Poly thing. So I don't know I did this right. He has.. 54,000 Tris.Poly.

Can a model with that many polygons used for something other than just images? Can I make animation clip with this character eventho he has so many polygans?

I also kept a low-poly version of him so I can use "Normal Mapping". But when I do "Normal Mapping" thing, it works if I see it in "High Quality View" in perspective windo, but when I render it, it looks funny... Help Plz.

Thx u
