I saw that, nice job... you might want to get Photoshop or Gimp or any other program to help you with the graphics... Photoshop is good because you can work with layers... take them of or work on something specific without having to redraw everything.
It could be a little confusing at first, but I am sure you can get around it! If you don't mind cracking older version of programs (Adobe Photoshop CS3 - that means if you can't afford it) I would recommend a version that is not sold anymore. They are usually stable and there is a lot you can do with it. I know cracking programs is bad, but my little philosophy on it is simple, 3 rules: (before I get accused of anything and everything...
•You don't make money using it, why not!
•It is an older version they don't provide support for anymore, why not!
•The community can benifit from your work at no cost, why not!
So you are the judge... or you pass down the idea of graphics to someone that would like to help you (I am sorry I can help, I am no good with graphics...)
