Looking at this, I'd say you haven't forgotten how to draw at all. I can't spot any anatomy issues, the outfit's cute and so is she. I especially like the attention to detail to her thighs and the way the suspenders and spiked garters dig into the skin. (Sorry if that sounds creepy x_x )
But hey, if you're not happy with it, you're not happy with it. No biggie.
Awww, i dont think youve forgotten how to draw P: but i can relate to that feeling a LOT. I think she is fabulous! i love LOVE her eyes and her cute outfit!. The flow of her hair is cute as well, id love to colour her actually, if you dont mind? I ttly understand if you want to finish her first though <3
