Thanks for the encouragement. I think my main problem is that I don't know how breasts work, so I can't draw a body properly. After all, it's not like I go cruising around staring at peoples' breasts all dy. :p
As for the face, She actually is supposed to be VERY tomboy-ish. I wanted to approach her design like a typical male lead rather than a female lead. Her personality is supposed to be very masculine. In fact, the only thing that should make her different than a man is the way she looks.
It's kinda hard to get my point across without some illustrations, though, which I'm working on. Some stuff with her riding her Vespa while swinging a sword, shooting, fighting, etc.
Interesting motorcycling attire...
Ah, don't worry, you'll get women eventually... The only advice I can give you is that women, even realistically drawn women, have much softer features then men do... Her mouth wouldn't be quite that big, I don't think, and her nose would definitely be much smaller. She also would have a more slender neck and body (the legs are fine, since they're covered by pants)... And maybe a more feminine hairstyle? Unless you want her to look fairly tomboyish. She actually looks kind of feminine in the sideview picture you have up near the top--the little ponytail really helps...
Just keep practicing, okay? I'm sure you can do it!
