You need to use smooth shading more. The blades have visible triangles and they look kind of ugly because of it.
Cool idea and all... but... that dagger that you modeled is clipping into the hand.It bothers me... I'm staring at it, wishing I could fix it with my mind!
i have fixed the model, i realized that too.
Probably just need to smoothshade the diagonal on the square sides of the blade. I saw this project before, seems really cool.
