With this design, I had noticed a ton a cutesy art becoming more and more mainstream on many shirt sites, threadless included.
I figured I would throw my hat into the cutesy ring, and created these imaginary characters doing imaginary things.
Turns out it worked, and they printed these on kids shirts even, which I think turned out the best. I bought a bunch of kids shirts for all of my friends' kids.
This design took the least amount of work, probably going from nothing to complete in about 2 or 3 hours, but that just shows that its all a matter of opinion in the end, and not necessarily how hard a design is to create.
