this seems like a project you should pick up again some time!
I was only wondering one slight thing... is the edges realy that steep? take a close look around the stairs, it looks almost like you would die if you decided to jump from the ledge :D
The ledges are about the same amount of tiles high as a house, so I do think you would die :(
Unfortunately I have neither the time nor the drive to continue this project, its a few years old, but I might get around to uploading more NES art eventually.
I wish I were this good.
To be quite serious, it doesn't immediately look like it belongs on a NES, which should be considered a compliment. I actually wouldn't mind seeing these used for something.
seriously for a hack it could actually do nice for a background
