This is the best piece of art I've seen today! This is so awesome! I love the colours, the red cape and the overall feel!

@sonicspin: I have made a first update to rework the front rock on the left and the pic in the middle. I mostly removed the ugly outlines, slightly reworked the shape and added some color variations.

@sonicspin: thanks for the comment.

The right side is the one I started with and the one I have spent most time in. So I am glad that you like it. :-)
I still think that something should be done to add more depths to the vertical cliffs.

Regarding the left side, I had first done a first version but as I wasn't happy with the front rock, I fully redid it.
It was probably a mistake ;-) I rushed to do this modification and it is clearly not as polished as the other rocks.
Moreover, and maybe more importantly, it doesn't follow the same style as the other ones (it contains a lot of curves, while the other rocks are much sharper).
 

the right side is wow! but the left side, the front rocks are a bit...ehhh, although the other ones in that side are the same quality as the right side, so...hm? I think you need to do a small revision ;)
