Aha, actual mockupry. No comments? I have some quick comments - the walkable ground is almost indiscernable as walkable when in front of the rockface tiles, case in the point: left sceenshot, bottom middle platforms. I almost missed them entirely. They appear to bump out from the rockface at all. That's a huge problem. The grass coloring doesn't mesh well all with surrounding colors; looks neon. It think your greens in general need toning down. And those rockface tiles need more variation tiles to break up that monotonous repetition, yow.
