I wrote up a huuuge post for your last thread, and then my computer froze and I lost it. I was upset. >_<; So, let's try again...
First, I want to say the Christmas picture from your last thread was amazing. I looked at it and went, "omg that's good foreshortening." That's not really on-topic, but I felt it ought to be said.
Kevin: I like his expression, his mouth is well-done, and the anatomy is mostly pretty good. However, it looks more... rushed, than most of your art. The eyes are too close together, the jaw is too square, the shoulders look off (the one further away from the viewer, especially, looks like it sticks out too far, to me) and his waist is too skinny. I seem to tell you to draw thicker waists every time I crit your art... x3 Sorry about that. ^^()
Francine: Again, you draw fantastic expressions. ^^ But again, it looks rushed. Her eyes are too high up on her head, I think... and it looks kinda incomplete. ^^() I do like the leaf, though.
Keira: That is one giant cigar. =o Anyway, I like the way you drew her mouth, her glasses, and her eyes. Her head looks like it could be just a tiny bit narrower, maybe, and a little more detail to her ears. The hand is really good, but the thumb needs a little work. (And you could make the cigar look a teeny bit less phallic, if you tried. <3)
Maria: Again, her eyes look a little bit too high on her face, but I think that's the biggest problem with this one. I love the goggles and the peircings. :3
...Have you ever really refined a sketch, inked it and colored it? (Wait! I went to your DA; you HAVE done so. x3) But here, I've never seen anything but sketches from you. ^^()
