Unfortunately after all that time spent on cave and changing and developing mountain my group changed the idea. Apparently the cave is not gonna be used in the game at all. Instead we are going to make a sky level and the perspective should go well with Max's sky temple which is very different from the sketch I was relying on.

Also I had to make some sort of the tower instead of mountain. So here is what I thought would work.

Guys liked it better, but wanted me to change the angles of the front diagonal edges (make it the same angle)  and add one more.level to the tower. Also Max had the yellow tiles done in pixels only (no vector), so I had to redraw it as well. Also guys wanted the stairs to be straight (same width on every level). I mentioned that I might add some extra details like a handrail or something.
