Thats a cool style.
Ummm I not so much an artist so I dont really know what you have in mind, but I like the font. As for the fish, can it be reshaped, so its not so tall or maybe make it slightly longer.
As far as the fishes features go, maybe a smile. The side fin looks good. Possibly gills. As for the dorsal fin I think it needs to be more like my avvy.
Is the fish in a puddle?
Also what program are you using?
