idea behind "Turtle Pie" entry

Threadless has been hosting a design contest for the Teenage Mutant Ninja Turtles. 25th anniversary.
Man, I love TMNT. Saw few glimpses from the old cartoon of the 80s.
But it was the 2003 show that got me really hooked.
New one on Nick, really REALLY love it.
Unfortunately my entry wasn't good enough for competing. Guess it still needed work.
This below is the finished design:

What inspired it? Well the idea is this:

 

Yep, just finished the comics today. Also on deviantart.
...I really REALLY need to finish the Eruti test comic.

If I got a Society6 or Zazzle shop, would it be a bad idea to use this rejected design?
More importantly, would anyone even buy it?

Ethelmay character sheet, DONE...for now

I'm done with these character sheets.
But then again, I think I'm putting waaay too much in these.

And...the test comic...I know...need to get that out.

oooohh! Ethelmay possessed?

Possessed? What madness are you drawing InYuJi?!!!

Actually, yeah. Being the prophesied "Harbinger" (title pending), she acts as a vessel for fairies, the head fairies. She can call on their power, but only for a little while. She has to be careful, because some certain fairies want control over her.

But yeah, I changed the spelling of her name. No way her grandfather would be able to know a chinese name "mei" meaning beauty or plum, something. So I decided to be random and say she was born in May. So unoriginal, I know.
