Out of beer
I like how you did the bubbles and the area where the fish hits the "beer surface" is really convincingly done. The fish itself is well done and I like the color you chose for it as well as the glossy, wet looking highlighting.
You could added a bit more "watery look" to the surface itself though. Except for the bubbles in the lower half there is just a barely recognizable color variation going on to suggest that it's actually a liquid. I think you should have made that a bit more visible. It's even less visible in the top part so it almost looks completely like one kind of yellow in the background, but at least there is something happening.
So art-wise I think it is a clear ten, but you could have done more with the composition. I like the elongated format however and of course how you incorporated the thumbnail.
