Coralline Sculpin on orange sponge

What's good:
lighting, fish's expression, focus, exposure

What's bad:
the composition has the fish too high in the frame (if the fish was lower in the frame, the dorsal fin would be visible and the detail of his lower jaw would be more evident)

Other notes:
I only got one shot of this guy because he dashed away right after I took it. The framing has the fish too high because I was diving shallow (approx. 10') and the surge was bouncing me around.
