A typical non-conformist dress-up doll...
Graphics: A nice first effort. Alexander's proportioning is a bit off, with points and curves in slightly odd places, and lines subtly conflicting with each other instead of working together to suggest a unified shape. You see a lot of drawings like this from new or young artists... The good news is, it's the sort of thing that one gets better at, with practice.
Style: Goth can be cool. And some of the clothes Alex has given this doll are kinda fun. I liked the striped shirts. Unfortunately, I used to download kiss dolls all the time, so I've seen all this before.
For your next goth doll, Alexander, try giving the shirts different-lengthed hemlines. Maybe add some folds or wrinkles to the cloth. Some of the clothes should hang off of the model's body in places. Very few, if any of the garments, should truly be skin-tight.
Also, name your doll. It's a small thing, but giving your character a name would have helped a lot. A submission entitled like "Dora VenomLace" or something is much more interesting than "Random Goth Submission #3." A little thing like a name, and hints of a lifestyle, (What's her favorite food? Add one to the doll.) can add loads of personality to an otherwise mediocre doll.
Interactivity: Everything works, and although the garments are skin-tight, they line up well enough. IMHO, snap-on is the way to go, but some traditionalists enjoy the simpler method.
Overall: Average doll. You can tell some effort was put into making this. But it wasn't anything remarkable, and the drawing style looked very rough and inexperienced. That comes with the territory, though.
If I were you, Alexander, I'd call this submission a success, and start up a whole new doll. One with a completely different pose and everything. Maybe try copying an artist whose style you already respect. It'll teach you a TON of subtle things about anatomy, perspective, and suggesting a 3D shape that are difficult to learn any other way.
Those HOW-TO-DRAW books would be a big help too, if you're not too proud to learn from the anime and disney conformists. ;)
Best of luck to you in the future, Alex. I'm looking forward to seeing more of your work.
