This will work on any colored shirt. Horrible pics. Will re-upload
I guess everyone will have a different opinion, and not to insult the work you put in(nice of you to offer your help and design work to the community here. I personally don't like these at all, especially the word "addict", no way in heck. And the colors, yellow, white, red, green, that color scheme doesn't make much sense compared to Analogous colors such as green and yellow.
Although I see some like it better than page3, so that brings up a question, Are we all going to design shirts, and keep changing the design? (Rhetorical ?)
Because
that seems like a recipe for this to never go anywhere, some will like some won't, some want this some will want that.
Think Mike will have to make a choice, and whoever wants them will buy them, maybe put up a poll or something.
I wear a tie and long sleave, or tshirt, don't like Polos, someone else will want polos.
Just rhetorical musings.
I do think offering to many options or having the az community design this, there will be so many options, less people will end up getting shirts because the design they saw/liked wasn't offered.
If your design was the only one shown and offered I might buy one, but after seeing a design I like much better I probably wouldn't buy this.
