Hey. Properly define the lightsource, and try some selout/aa with the teeth to cut down on their jagginess. The right horn seems much wider at its base than its counterpart.The fore-legs need better definition, look up some reference picture of goats and their skeletons, i recommend.

The far hind leg seems fatter that its counterpart, as does possibly the far fore leg. The angle of the mouth doesnt lead into the throat, but rather towards the ground, maybe rework that a bit.

The creature also lacks texture or anything of real interest detail-wise. The transition from the fish skin to the goat needs more work, though it's still early days. Also, maybe give the creature a goatie beard.

The inside of the mouth needs detail. Even you're feeling up to the challenge, define the angler-light as a second light source.
