hello, this is my first post here. been a lurker for too long

I'm doing this mockup, its supposed to look like the courtyard of some XVI century palace in spain. the character is some kind of rogue (don juan) who makes his way into the damsel's rooms. the game would be kind of like metal slug, with some prince of persia sword fighting elements. I have 3 different tiles for the floor part, while all the rest is just a big tile made of 32x32 tiles. I'd like to make this into a flash game, but I'm not good at programming so I don't know if that will ever happen. Anyway I'm planning on animating the little dude and his foes, but for now I'm just doing this mockup. Maybe that way I can "sell" the idea to some ActionScript programmer.

the look of the background should be more detailed than the character. I'd like to break up the monotony a little bit, right now it's too stiff, I might need to get rid of the black stripes in the floor. I need to work some areas, especially the small trees or bushes, and maybe and some AA to the background. I could optimize the pallette a lot, too. the wall needs some spicing up too.

I'd appreciate your advice and critique very much, thanks in advance and my apologies for my english writing!
