This is beautiful, and I've always been a huge supporter of your art and such, so I hope you don't mind a little critique here.
The thing that makes this questionable to me is my knowledge that tails come out of spines, not - to put this delicately - the cleft between the legs. I think this would be worlds better if you were to change the position of the tail.
The detail is amazing, though, and the colors are gorgeous. <3
