huh, since when copying is considered bad? people draw and copy nature, photos, so why not 3d objects? I can admit I looked at screenshots and copied them but I don't see how it can be bad in any way. also I can draw without any reference, but drawing my character I felt like it would be more accurate.
and just to prove a point, I did this today:
it's not based on screenshot, but I looked at my character from time to time, well I'm reeeeaaally sorry I haven't memorized all her features :/
not to mention my whole deviantart gallery proves the point, lol
