Usually I hate the way my RPG "mountains" or "hills" turn out, but this isn't too bad. I want to fix the square corners on the tops though, and give the steps more character, less uniform.

Edit: improved the stairs a bit. Now at least they look like stairs and not a ladder. I'll work on it a bit more.

Looks great! I actually see a real staircase :) I also saw a similar work - when a character crawls on a rope inside a large vertical pipe (curved wall) - here IGMC MANSION TILES. This is a really great idea with lots of options for quality mapping. Thank you.

doesnt look too bad!

hey do you want to make a game together?

Yeah if the tiles for the stairs could match it'll be better. 

It looks pretty good =]
