looks pretty sweet, but the dislocated jaw only looks good from 1 angle, otherwise it looks weird. Try tone that down a bit, you can always use norms to add some depth

Gills are a bit messed up.

We fish take pride in our gills.

Also what are those two little blobs infront of the gills?

When the female angler fish mates with a male, the male dies and leaves the female it's testicles.

Also,

Scales. Now.

HAZ POTENTIUL

Those things are scales. The 3 semi circles or w/e

i thought it had suddenly contracted leprosy.

losing the plot imo.
scales would be too much detail, and would totally kill the character.
think fins on sides top and back would finish it off.

looks alright =] :]

wow, i love it man. the cleanliness of it blows my mind.
but, i dont like how it looks like a mutant 3_3

Ewww! No need to mention that

Doesnt look like much of a fish :/
I dont think a fish has 3 faces, and it needs more colour

i like hte front and the back faces that top ones really out of place though looks not bad though :L
