It is an improvement from your last one, I agree - even though your first one was much better than my first. xD
I have a couple tips that might help you. ^_^
*Shade the skin darker under the hairline and anywhere else where clothing meets the skin. This gives more DEPTH to the doll, making it look more real and almost 3-d and less like a how a paper doll would look. =D This isn't necessary for those starting out, but it's something that really improves the doll and only takes a couple seconds.
*Some of the folds are a little weird looking. The ones at the bottom look pretty good, but the midsection ones look like they aren't loose enough. Loose folds are more diagonal (/) and less horizontal (-). The angle of the folds influences the shading, so tight clothes would have horizontal folds, and baggier/looser clothes have diagonal folds (or vertical, when talking about the bottom of a dress).
*There are still some unsmoothness going on with the outlines:
See how the first curve and line are much some "smooth" looking? Try to work towards that. ^_^
*** The greatest tip of all, edit, edit, and EDIT some more! If something doesn't look right, try and fix it. Then, if it still doesn't look right, fix it again! :P Editing is the most crucial part of doll making. It's like editing an essay - a little editing can pull you from a B to an A, no problem! =D
