I agree that her hands look too small and also (could be me) does her head seem a little too large for her body?

Starting at the top. Cat ears! It's just a suggestion ^_^ On the hair, see how I've slightly overlsapped the inside line of each hair bang? Adds 3d look to it. I also made it obvious where each band is comming from (shooting out from the center).

The hair on the back of her head sticks out nore to give it volume. Eyebrows were added. Mouth was raised so here's lep gap under the nose. Her right jaw line was brought in considerably. That's what happens when you draw a 3/4ths angle- you see less of one side, and more of the other. If it were a straight on angle, you'd see both sides equally.

Her right shoulder was brought in a little. Re worked her left arm/hand. The arm narrows at the wrist. From here you have two sections of almost equal lengh - the palm and the fingers. A lot of people make to mistake of drawing a tiny palm/fist, but it's important to make the hand long (sometimes two thirds of the forearm's lengh), especially with female characters that have delicate hands ^_^

Lastly we get down to the legs- I've added in the lower limbs, just to show ya how they might be placed. I think I should have drawn them longer though!! A lot of novices draw stumpy characters with big heads, so do one better than them and give your girl characters a long, figure ^_^

Try taking all these things into account for next time. In fact, now you know what to look for, so you've got no excuse!

Also, make sure to watch out for other artists that have made faults- even the pros make mistakes, so if ya base work on theres, make sure not to pick up their problems. Hope that helps
