"Ana":


"Cloud Strife":


"Aiacos of Garuda":

The third picture is the most anatomically correct, from what I can see. The other two, they're not bad. I would practice faces and just proportion in general. These pictures aren't overly indepth, save the armor, but practicing those basics will help. I will say that on your third picture, his arms look a little skinny compared to the rest of him. I mean, he's all buff and armored with these wimpy arms that are half the size of his neck. Practice hands, not matter how annoying they are. Most people hate drawing them. You may wear out the paper in your pursuit for "pretty hands" but you'll get a bit of a hang of it eventually. Once you get there, it can only get better; it may take even longer to do it with more ease, but hands will get better.

Crimson pretty much said everything, I guess. I fail so much at humans I don't even dare draw them.

Usually people learn to draw realistic humans and anatomy first, and then they specialize in a style, such as manga. At least that's what I've heard. ;p

And yay for Saint Seiya!

Don't stop drawing.

Actually, I started drawing from Sailor Moon comic books. XD I practiced for hours every night, and that was as a second grader (my god I feel old now).

Yeah this drawings are about 2 years ago...
I don't draw as much anymore...
Too much study and work... >_>

But i see what you mean....
Thanks for the comments.
