I'm having trouble finding art so I spent most of my time at NASA and Google images.
This is the result of my mock designs.
It's still not perfect but you really have to see the design of the code to appreciate it.

What do you guys think about the graphics?

I plan on extending it to a multi campaign chess like RPG.
By multi-campaign I mean that you can set up the board differently among keeping your characters after battle to use in other battles.

Eventually I may extend it to a multi player thing.
It's supposed to follow Cas's(Why do people call "Princec" "Cas"?) Puppytron formula to make it fun.

If anyone has any artwork which is power of 2 could you please tell me where to get it? Thanks.

What do you guys think about the graphics?

With all the blending, it seems a little bit difficult to make out.

(Why do people call "Princec" "Cas"?)

Because it's his first name

How should I go about the blending?
Should I make the characters stand out by glowing?
Can you give me tips about the way graphics should be displayed?
