Turtle Sex T Shirt Design

Apparently this is a t shirt design for a band after this guy/girl saw my Turtle deviation on DeviantART.

They left me an email saying:
"i saw ur popular turtle on deviant art and im making t-shirts for a band and i was hoping u could make one haveing 2 turtles haveing sex and the one on top have a huge smile


just wondering if its possible emial me back soon"

Judging by the spelling and grammar mistakes; I'm guessing this isn't a very popular or good band. But whatever, if this does in fact get put on a t-shirt, that at least one person wears, that'd be cool.

Just hope the drawing fits the requirements of the email.
