Nice work on that katana..i think the detail in the modelling and texturing are spot on.

talking about my earlier 'beer can' image
Aaah thats because i always try to keep things as low poly as possible .better for rendering times. maybe 1 more subdivision would have been better for a still image you are right. there is some noticable edges there..i kind of thought it would not be noticable through the camera blur.
I hadnt really noticed the inner texture there, my monitor was set a little dark.
