I modified the fish according to your directions ( I guess that you meant dorsal fin - not dorsal gill). If something is still wrong you can use drawing feature. It lets you to draw over the logo entry to show me the spots that need attention.
The head needs to be sloped down more and less rounded. The mouth is also too wide and needs to be smaller. Also the dorsal Gill needs to be more connected.
I'm only allowed to give my contact data after the contest. Maybe try to write what's wrong with the fish. It's close to midnight here but I can correct it tomorrow morning.
