thanks. those are some helpfull comments.
As for the colour: it should be something to match my red happ buttons. (any idea which rgb colour code i should take?) Apart from that i am open for anything. Looking at your great artwork you must have some suggestions

About the button/joystick decals. The simple holes on the art are just the drilling holes so they wont be vissible. If you are talking about the 'oval circle' around the group of buttons: i am having some doubts about that too. Somehow it seems a bit 'off' from the rest of the design, although i am not sure what exactly it is i dont like about it.
About the character art: i tried to find space harrier art with the biggest resolution i could find, so i ended up cutting these out of a arcade flyer on the web. The pitures here are rescaled ofcourse, and when i took a look at the art after pressing: view -> printing size it looked pretty ok. But vector images would be even better off course. Would there be any space harrier vector images available? These pictures here seem quite hard aka impossibe for a noob like me to vectorize.
About the name: totally agree. much better
thankyou!
