tentacles are my fav!
I only gave you a 8 on this because (for me) I feel like I want to see the legs in the water a little wavy and distorted. Maybe you tried this and it doesn't work for you, but if you haven't, give it a shot!
But again, I love the rendering, the little details of the sea shells on its belly, and the little kid in the Lock Ness monster tube, classic.
