I like #29 and #33 now that the T-shirt icon has been added to the "O".
Can you play with the white color of the t-shirt? Some people can recognize the shirt right away, some people don't. The drop shadow definitely helps, but some other element might help even more.
The drop shadow might also cause problems if we try to dress the logo up during season changes. Either way, it has added a nice touch to the t-shirt.
I would also like to see #28 with the T-shirt in the same blue as the rest of the logo (or maybe another color).
The lime green gets confusing and hard to read.
I would also like to see both logos with the gradient highlight that was used on
#3.
So far you have the cleanest, most professional, and subtly fun logo out there. We appreciate your great ideas. Thanks!
