Nice work, man, and thank you for the input on my design.
I really like the very subtle shadow that makes the OK sort of float off the tee.
I think that if it goes to print you should consider moving the placement up a bit. More on the chest, less on the tummy. Gentlemen don't usually think about it, but we have to be conscious of how are design interacts with ladies' chests. My buddy's sister pointed that out to me a while ago. Good luck, dude.
I like this alot!! ...it would be awesome for kids tees too! I have a 3 and 5 year old (boys) and it reminds me of them....it's always "ok ok ok ok...ok mom." :D

Pretty self explanatory.
