I'm still playing around with the artwork, trying to figure which would look better when in button format. I like the lettering looking more "blown out" on the left, which is similar to what I did on the cover. The image on the right: the lettering reads cleaner.
I also don't know which size of the "Bobby character" I want to use yet.
The smaller I make him, the bigger the bubble becomes, (which is the main idea.)
But if Bobby's image is too small on a 2.25" button, it will be harder to see and figure out what he is doing. I'm going to test out a few samples to see what works best for a 2.25" button.
