Welcome to Gaia! ::

So this is just some random stuff I've done.

That's me and Doglover4eva (we know each other in real life.)

Random. Very much so.

My first attempt at a boy!!

=D

Me and Dogluver4eva

Me and Dogluver4eva, she drew the dog and my scanner went all wonky.

Hm...The hands/feet often come out looking a bit smallish on your figures. The girls are rather, um, flat...females should have an emphasis on hips and some form of breasts (unless they are supposed to be 12 or younger), an area I also have to work on often. In the one with the dog, the light haired girl is oddly thin. A little practice with anatomy and you'll be fine.

The faces are cute, as are the over all designs of the drawings. Keep going!

Well, in my experience, if the feet and hands are about the same size, your off to a good start. And if the hands are about the size of the face (eh, chin to mid forehead) then all the better!

Your specific hand/foot practise looks pretty good, but make sure you apply that to the rest of your art or else there isn't much purpose in practising it in the first place. That foot does look quite good, but the hands still need some work (the thumbs in specific are positioned oddly). It looks like drawing hair is probably your strongest point, and the head shapes are alright for the most part. I think the anatomy on your boy looks best out of all your pictures, though his neck looks a bit long. The cat girl in the picture below also has pretty decent proportions overall, though again the neck seems a bit long; also, her hips could be wider and her legs look awkward.
I dunno which of your pictures are newer and which are older, but I'd look at those two as your better works and try to apply that stuff to the rest of your art (while continuing to improve, of course).
