The coloring and shading are excellent. The limbs are posed nicely.
But I have to bring attention to intamites anatomy. A woman's vagina doesn't stop at the front, it gose along the underside and ends very close to the anus. This depiction makes no sense unless it was intended to be a sticker slapped onto the front of the pernium in place of actual female genitals.
In short, study reference and learn how female anatomy works. It takes less then 5 minutes to find a good chart on google images. I'm sorry, just so much gose to waist for an easily avoidable anatomy error.
