Good concept! I often feel I have the memory of a goldfish, or I might feel bubbly like a goldfish... But I dont like the expression of the girl. I would have loved the tee if the face was different! More sympathetic maybe, cause now she look kind of bored?

Nice idea. I never really have the whole 'Fish For Brain's feeling, but sometimes my head gets clogged up where I can't think about anything complex, and this sorta reminded me of it. But, as the person before said, Maybe if you redesigned the shirt, I'd vote higher.

This fish (and the fish alone) is nice.

Fish IS good food for the brain... or is that an old wives' tale?

i think this is a good idea, i just am not sure if i like the little bubbles that extend outside of the head

i really do like the concept though

I like it because I often have Miss Fish on the brain.... $5

Very clever, good design and I like where it is on the shirt. Nice job.
