awww sexy... I'd make out with it but... you know... internet. and now to the useful (hopefully) part of the reply: the crit. The shoulders look pushed out a bit too far, further than the anatomy/pose should allow. Seems like maybe the pecs should wrap around the sides a bit more before giving way to the non-muscle rib…
He's undeniably cool, and the modelling is executed wonderfully, but something about his design bugs me. He just doesn't seem to make sense anotomically. This critter swims in the ocean, or crawls along beaches? I'd really like to see you push the evolution of the species a bit further than the centaur-esqe he's got going…
