Thank you for the very helpful answers. (:
And it seems like I got it wrong with modelling... if that blade has too many polycounts, then what am I supposed to do with this model... crap probably. ;D
Well, just training aswell. Made that body in wings3D and just smoothed it with modo. (Modo's too complicated and I don't have enough time to spend on training... I prefer Wings3D, which is very simple in my opinion.)
If u guys want I can show u the wings3D version of same body later, when I'm home.
P.S.: Yes, this char of that game has the same blade like I posted above.
