Andre,
I see where you're going with it.
I would suggest trimming the glosso as it detracts from the mountain feel. Keeping it close to the substrate as mentioned above would be good.
The HM seems a bit out of control to me. It should be trimmed to accentuate the shape of the driftwood or rock (I can't tell from the picture).
Lastly, I think the crypt on the right (might be wendtii) throughs the composition off balance a bit. I would move it to the background or all together.
