Classical

Excellent work on your Classical Greek Bust, Amurphyr, yet, I've got one very, very small request: Why don't you do yet another Classical Greek Bust, in 30 seconds, flipped vertically, if you please?? Because, your right hemisphere will pick up on that photo right away. Hope it totally helps.

Looks good, you're definitely improving. All I really feel comfortable pointing out is the base that's a bit warped and your crosshatching in the center of the torso. I think these strokes just make it look flat, thrown in willy nilly to "fill out" the blank space. If you find it difficult to make straight lines I suggest looking up drawabox.com, amazing but tedious excercises. Otherwise I like it, great job

I think it looks great! But the lines that go ower the face look a little weird, try prehaps erasing the guide lines whit a smaller eraser? So you can really erase them whitout risking to erase anything eles.
