So I'm thinking about making my own playmat

I'm starting to design my own playmat and I'd like some criticism / ideas on what to change.

Right now, I may remove the text in the corners and remove the Angelic Destiny picture for a green gradient.

Here's the website and it says "don't let anything important get with in 1" of the edges" and that's why things are off-centered, but I'm still working on everything.
