I don't usually "Review" art. But I love your style and want to help improve if I can.
The over all image is fantastic. But the only things that I can say throws me off is the penis. Looking closely I can see what you did but from a distance it kind of looks off, like literally not connected to his body. The only other thing would be the arms look a little to skinny when compared to the legs. But know that your shading is great and the character herself looks wonderful.
