@Manupix:

Yeah, I guess the lack of (visible) teeth and the general non-pointiness (is that even a word?) of it makes it look more like a dolphin or something. I mostly referenced to Blick's Shark, I probably should've used other references too, missed a lot of important points. And the unhappiness, well, I tried to make it look a bit sad and/or serious as a contrast to Blick's smiling and sly looking shark. IMO saints usually look serious, at least in Christian imagery.

Now that you mention it, it does look a lot like a sun, and I can't get that image off my head. I should really do something about that.

Yeah, the text panel is kinda silly. I thought it would be pretty cool to have, like in one of those frescoes or murals that have latin text on them, but I got pretty unimaginative and lazy at the end. Now that I look at it afterwards, it really doesn't work (at least not in its current form).

Thanks for your constructive comment and tips, might try improving it later if I have the time.

I like the bottom half ;) but the top half has some problems.

The shark's head doesn't look shark-like at all; use references of cartoony sharks.
Also if he's a saint, why does he look so unhappy?

The halo doesn't really look like one, without the title I thought it was the sun or moon.
It's supposed to shine, so it shouldn't have an outline, and its light should affect the shark somehow. Probably the brown isn't needed too, but a brighter highlight might help.

The text panel is inconsistent, because of the thick outlines elswhere. What is it, ands is it necessary?

 Very nice!
