Very interesting idea, From the thumbnail I thought it was a tree poking through some storm clouds at first 9which would have also looked really cool I guess) Though it doesn't seem to be touching ground here and looks more like a tree from the outside is leaning down into the cave (sorta like a downwards bonsai...I got one like that ) The lighting is also very nicely done
Oh boy, this this epic. How I wish it was real. You capture one of my deepest fantasies, to have a secret spot such as this. This is so wonderful. I adore the calmness of this high art, as it also adds mystery of nobody being there and fading off on the sides. And the depth you gave this really magnifies the wonder that is just beaming off of this. You are sir are talented.
