Very beautifully done if I might say.
This almost looks something out of James Cameron's Avatar (Just minus the blue people).
Also. That blue thing in the tree.
Is that supposed to be it's heart?
Or is it supposed to be something else like a fantasy creature being hatched like an egg, or a radioactive power source that screws you over if you touch it, or a portal to another world?
If someone could let me know. That would be most appreciated.
Aside from that. A fine job done on the drawing. God bless and have a nice day.
