Man, awesome concept here.
I think the purple geist-flame is a really nice accent, especially how tou used it in some interesting illumination tricks of casting the purple light across the figure.
This actually makes me think of an interesting mimic/dryad symbiotic creature, where the the mimic serves as the transportation/planters pot for the dryad's tree.
Overall, I see a real passion for the monstrous in your work, and I deeply appreciate seeing your efforts.
Thank you for making this.
