Awesome! Though if I may make a critique: I think the vibrant blue (especially the section near the bottom left corner) clashes with the rest of the colors just a little bit. However, I really like it and am jealous of how much patience you must have to do these paintings.
Dimmed it a little, don't want to loose too much of the luminescence of the growths though. As long as the yellow light at the entrance is the most saturated.
