Keep trying
Big ass is nice, even thick thighs... but she looks like her thighs are that of a fatty. Also her face doesn't look anything like it is suppose to. Her feet need work. And you need to work on your color tone changes- when, where it is suppose to be. I can see that you have some skill, but you need to take your time and focus.
I went to your profile page to check out some of your art, in hopes of getting some good tips from a master artist. Surprise surprise, you had no art and no flash to look at. A critic who does not even practice the work he criticizes.
MY EYES
What the fudge happened to "perspective"? I mean, look at the thighs and face!
Apart from that... its alright :P
D:
... it scares me, mommy.
The calves are toothpicks, thighs are rippling masses of gelatin. Don't get me started on the hips. Translation: legs overall crap.
Torso... the torso... it's.... Translation: the best parts of the torso are the unseen parts.
... and the arms... oh my... Translation: the arms look like they were sculped from pudding by a bored frat boy.
The face is undeniably the most wrecked part right after the thighs. It looks like it belongs on a woman 300 pounds overweight that got lip surgery and a face lift. Translation: BUT-`ER FACE!
Now that the worst is over, I'll tell you what's good:
The coloring job, while the lineart is completely balls, is pretty spanktastic. Disptie the generic background, it has a sense of stylelization that persists for most of the figure. The only failings are the shadowing of the tail and face(that shit needs to stay in the dark as much as possible).
So here's my suggestion to you, mister Old Anime fan: GET SOME GOOD REFERENCES LIKE A MODEL BOOK OR SOME SUCH CRAP.
After that, you're golden...
