Composition and shape design help

[slash razor]

I think all your rocks on your main pathway all look the same try to vary the sizes large medium small atm they mostly all small which throws the viewer off also its not showing depth and scale, the closest cliffs on the other side maybe make the path wider you could maybe add a character to that path with a torch? Birds flying to fill in blank spaces?
Showing depth is a biggie to me I could do a quick paintover to show you what I mean... If you want? Let me know

Otherwise great job great idea love the colours... Sounds like a cool course your doing....
