Has a distinct blue tint to it which makes me think your white balance was off... What time of day did you shoot this? The lighting is a little harsh.

I like the boy in the fish, however keep an eye out for distracting backgrounds, can combat busy backgrounds with changes in perspective or shallow depth of field. Which involves setting your camera to aperture priority perhaps 5.6 or 2.8 or if have point and shoot camera use portrait mode, (thats the little face) GOOD LUCK
The wording for this challenge was vague at best, so I am struggling to be fair. This is a lovely photograph, but the way I understand the challenge it doesn't fit. But I do like the photograph!
I think if you'd spent a little more time and tried some unique angles, and different POVs, you might have had a real winner here. In my experience, the more you experiment, the easier it is to find more unique and fancy shots as you go.
