I am 'greatly' impressed by the sheer amount of effort you've put into these backgrounds. Exceptional work by any standard, and certainly commercial quality. Bravo. If I didn't have the ATC millstone around my neck as well as my own game, I'd be happy to help you out with this project, but I just don't have the time. Personally, though, I think you've done a fine job doctoring the Indy sprite, and I see no reason why you shouldn't use it as a template for all your characters (unless you want them larger).
