Well this one right here is wow and very lovely. The way you've drawn the hair is my favorite part, as there is lots of shine and hair texture details with a touch of different coloring here and there. I like the way the hair is outlined as well, it gives you a nice almost anime art style with that hairdo. I think the overall body of this girl is nice. It is very sexy how you drew the vagina and breasts. The pink lips matching the pink nips was a nice detail and made it more sensual and visually appealing. I think you do a good job on your NSFW art styles. I like the eyes in the girl, almost like she is ready for whatever is about to happen and willing. The wings were nice and cute too, like a fairy as you were trying to portray here. Even the tattoos were pretty interesting. I do like how they all go down the side of the body is a nice consistent pattern that was very sexy to include on this fairy girl. Even how the tattoo comes off the body at the bottom was good and gave a more completed look.The only issue I have here, as well as others it seems, is the feet are a bit off. They seem unfinished because you've drawn this like it is a calf and not a foot. If you were to add some shading and textures near the end of the point, I think it would come off more as a foot and not this point like a calf ankle thing with a part missing. Overall this isnt a bad piece, but you need to focus more of the foot element here, more detail in that area would be good, but it doesn't take away from this piece. I think it is a good one as is, but that would be the only main area I would change or focus on the next time you want to try your hand at doing fairy work.
~~THINGS TO IMPROVE ON~~
Work on the feet area, just how you represent them, but good overall.
