Old piece, I know, but I gotta say something. First off, she is damned adorable. I want to squeeze her forever! A couple of notes on the design. The dorsal fin might work better if moved onto the tail near the base. That's where I tend to put them on my shark characters. The blowhole might work better if placed on the bridge of the muzzle just behind that white ring. In real dolphins, the trachea comes up through the skull behind the melon but in front of the brain case.
