Alright, you asked for a critique, so I hope I do this well!
This is a pretty good attempt - the top is pretty much fine, except for the next being off center (should be a little more left, so both shoulders are the same width).
As others have stated, the legs are way too long - each half of the leg should be about the size of the torso and hips together. Also, the right foot is a bit too long. I'd also recommend maybe making it a bit curvier - but that's more a personal thing, I find sharp corners unnatural looking (there's pretty much no sharp corners on people).
getting better but the legs are still too long for the body. i know winx proportions are off but she doesn't want to look off, if you get what i mean. the body and the shading is really good and the hands are v. good indeed
