a shirt which is talking for you ... seen from the front it asks WTF ? while seen from the back shouts OMG !

i don't like the brown other two are awesome though.

I think I like the blue-green-pink combo the best. Those are, after all, my favorite colors!

the question mark is cute, love the expressions on both!
$5!

I love these. Any more punctuation you're working on?

This is great! I'd like both images on the front of the tee like you have them at the bottom two images, i think it would make a stronger visual even though i love back/front tees. I agree, keep making interesting punctuation people scenarios.

cutie cute/...

This is cool, but as I said in the critique stage, the ! isn't exclaiming, he is chilling. You need to make the ! more dynamic/excited. They would also work better together as a pair in the front of the shirt, or even better for me as stand alone characters on separate t's. (middle placement too, I don't get the bottom l/r placement on shirts,) but that's just me.

The question marks expression is flawless $5 just for that.

love, love, love so much

I love it as it is. Not big fan of the sand color, but that's because I just don't like that color.

Simple and cute!
