Thanks friends.
Hervé , yes I work for .
Djflod, thanks for the ork

you inspired me my next modelling challenge... a "beautifful" ork
Eric about the stripes.... I really don't know what is it? I don't think its a mesh problem, It's a nurbs model and when I triangulate it with high density... so I don't know
Kurts, you really feel it too much dark, in my screen , all seems ok.Maybe I need to calibrate it. But the dark green part with vegetable cut is right just a silhouette.
thanks again.
