I'd prefer just the text. No pics. It makes it a little more universal that way.
And just a bit of advice...over the years, I've seen many people with shirt ideas, with threads that go on for page after page after page with all these people giving their different opinions. A lot of times, the OP just gives up. You'll never please everyone, so you might as well not try to.
I say, just choose something and make it happen. People will buy them.
