Brown to orange version
This one is more as an illustration than a logo.
It's not as good as the Table rock one but I still like it.
These colours look pretty good, but if you're doing a series I would try a color scheme that is a bit more different than the Table rock one. The green and pink was the best so far, but not entirely sold on the pink.
As for the illustration, I'd just suggest bringing in the bulges on the sides a bit so it is 'heavier' at the bottom, do you know what I mean? If you run a vertical line on each side the bulgy bits on top go further out than the base; i.e. top heavy.
