If you can't come up with something to put there for type, take the type out. Having "blank" on the shirt makes it seem almost like you're trying to say "insert trendy saying here", and just makes the shirt look retarded. I would like this design if it didn't have the text.
general rule: don't use type as a crutch to explain an illustration. most tshirts that are successful on this site are stand alone illustrations. good luck.
