Hi everyone!
Here is my latest project I made between other projects just because the idea suddenly occured to me

. The idea was to make a kind of alien tree with rigid outer bark skin, that protects its burning "heart". So here is what I finally came up with.

I also agree with papercut's suggestion, it would bring it to life more.
Quickest and easiest might just be hiding the edges behind some small rocks, or building up a bit of piled dirt that can be alpha-ed a bit. Some scrubby grass would probably be a bit more visually appealing, but also a bit more work-intensive. Could also be cool to check out lifting up parts of it to try and get some space underneath to let that glow show through a bit more.

Thank you for the idea, I really appreciate. I'll see what I can do with it.
