I like the effect you have going on, but the dude doesn't look very blended. If he's supposed to be swimming, maybe hue/saturate him so he's more blue-ish?
It looks like he's swimming out of the water, if you know what I mean. If you look at it, it looks like half of his body is in the water, and the other half is coming out. Its sort of like diving into the rift in that show stargate galactica. Half of your body is in one place and the other half is in some other. Do some more blending into the head. Now rate mine
thats pretty sick man i like that, id say just play with the color of the seal himself and it might blend in the effect a little more
this is a pretty cool concept! the only thing you have to do is blend the render a little bit more and it will be really cool! work on text maybee.. and thats it. Good joob : D
