nice character you have there ... i dont like the text or the setting though ... have you thought about having him surrounded by actual mermaids, kind of a "one of these things does not belong here" scenario? i think this could work with a fleshing out of the concept
I'd like to see the chair be some kind of shell or coral type of thing. Something from the sea. I feel the same way about the type, maybe add some scales in there.
I am super-happy about the type as it is... about the chair, I know where you are coming from, but I like the nonsense of it, if I worked more on it would be to make it look like a grandma's chair...
The main point is, you like him as a character? The stinky thing is off-putting or funny?
The very loud t-shirt colour that I used on V3 does not actually exist in Threadless, but that could please some. I think it works well either in on both shirt colours.
