This is a doodle, much like the ones that virtually everyone here has in their sketch books. Think about the ways you can utilize color and space on this shirt to make things more visually interesting.
This looks like a greeting card. It even has a greeting on it. In fact it looks like a greeting card I would give an old lady who lived with 16 cats and never got married. I cant click "i'd buy it" as a shirt though, because she only wears that one sweater bill cosby gave her after their one night stand 40 years ago. It definitely suits her tastes though.
It's about time there was something that didn't looked squeezed out of Adobe Illustrator on here! It's an actual funny tee, not something you see very often at all. Bloody brilliant.
