for a small space, nice detail

I used photoshop :3

What program do you do this on?

Lovely! =)

thats so cute D:, faved.

anti aliasing that creature should make it look better 

Nice underwater mood and good hue shifting for the light effect! Lovely!

AA stands for Anti-Alias, which is basically the smoothing of edges. Neglecting AA results in "jaggies", or obvious jagged edges that should've been smoothed. GO HERE

Loving the background. 'v'

What does AA mean?

Nice work, though I agree with Mathias, with some clean up and AA this piece could go from ''good'' to ''great''.

 you catched the underwater feel pretty well, but some underwater lighting distractions would make the piece more interesting.

Nice peice. AA is so bad it looks unfinished, though..

That. Is. Awsum!
