Opinions on Shirt I Designed

Hey! So, I just finalized a shirt design that I've been working on and it can be seen here:

I was wondering what PLounge thought of it, and if I should show anyone else it. I decided to make the profits I make at 0.5% so I make like a couple cents per sale, since I wanted to keep the price as low as possible.

Okay So NOW I've made a new site using spreadshirt (I always assumed it was just another expensive site). But found that I could take ZERO profit, and they'd charge, very fair prices, as well as give me more options for shirts!

So here's the site! http://cheddarshirts.spreadshirt.com/

There are currently two types of shirts, an american apparel, which is more expensive, but is the same as the previous site, and a gildan, which is much cheaper. How should I tell people about these?
