Lacking anatomy and shit perspective
Why is it that the leg that's supposed to be further away from the viewer is jolting out further than the leg that's supposed to be closer to the viewer? Furthermore, why is the one that's supposed to be closer to me smaller than the one that's supposed to be further away? Are her legs supposed to be disproportionate? If you were to rotate her to face the viewer, would her right leg be bigger than her left? Would she slouch to one side? Considering how her right arm is bigger than her left I'd say that she would most certainly be lopsided.
This wouldn't be a problem if both her legs weren't pointed at the same direction, as if you just copy/pasted them, but I know you didn't because her right shin jolts out further away than her left leg does, only except you actually decided to use perspective here, which it's too late for now, it's still bigger and longer than the leg that's supposed to be closer to me.
That V shaped emblem on her head is facing me when it's clearly supposed to be facing the same direction as her face; both ends of the emblem are the same height, width and they curl away from each other. It's just another example how how shitty your lack of perspective is.
She doesn't have a chest of any kind, no rib cage, no collar bone, it's just her stomach connecting to her shoulders. What? You were too lazy to actually develop a clear distinction between the two? Were you jacking off while drawing it? It appears as though you were, otherwise this piece of shit wouldn't look so awful.
Also, her right leg changes perspective between the space that's overlapped by her left leg, which tells me that you didn't draw her right leg all the way through, you just made her right foot an additional detail after you done with everything else beneath her torso. Terrible. Even so, that's not quite as bad as her left leg, where her shin faces a different perspective than her thigh, as though it's broken into that position. It's so bad it's unbelievable.
There's no shading at all. You could at least try and make this aesthetically presentable by adding substance to the coloring.
The detail equally sucks ass, why are her thorns tucked into her fingers when they're clearly supposed to be attached to her hands? Why don't her arms have joints?
FWI, intentionally promiscuous anthropomorphic pokemon = furry erotica. Congratulations you dolt, you're a furry.
Learn anatomy, figure out your perspective and just learn how to draw.
