designs look funny if theyre printed on the belly.... maybe do a wrap around the side, then its a good shirt

dont be afraid to use some color, this looks like it came straight from the scanner

At first glance the seaweed looked like tentacles; you might want to put some space in between the blades and the sub. Also, adding coloring wouldn't be a bad idea, so that you can really tell it's a sandwich. You could do it with just tan, pink, and green.

it's been done, both are pretty good, i prefer the other though.

i didn't scan this, i drew it in illustrator. i used color at first, but after it was finished i thought it looked better with just an outline.

bigger kids like me cant wear belly designs... nice drawing tho
