This was the initial sketch I had. The sea snail was floating, and a turtle was looking over the diver's shoulder. I cleaned it up some, and put more focus on my name.
Here's the cleaned up version of the header. Sea snail is looking at name, and there is more focus on name.
Second color study. I played around for a while, and the narrower my palette became, the happier I was.
You can see the final version up above, but now that I'm looking at it online, I think I may have to tweak a few things and put a better version up. I lost something when the pov shifted further away...and my line work got sloppy in a few places. I think my color could be more solid as well. (That's something I'm working on: flat, solid color.) For now, it works.
