That gives us a great opportunity to comment directly on your additions. You've made it richer for sure. Somehow, though, my brains are troubled by the mushrooms there, because it feels like they really, really don't want to be there on an exposed rock. If you had an old, "rotting" tree trunk there somewhere, maybe just a bit of root work showing and the mushrooms grew on or around that one, it would feel more "real", or imaginable, you know. But the mushrooms are not entirely necessary to begin with, even if they look cute.
You also have a very elegant a pleasant focus on the little waterfall in the perfect spot and the mushroom area almost distracts in a way, pulling the eyes away from the waterfall.
I know, sometimes it's hard to imagine what it's like for someone to see your painting for the first time. You've become so familiar with everything and want to see more, add more, fill it up. But it's tricky to improve on your highly artistic intuition, which you should really respect greatly. I can tell you that I do very much!

Hmmm...maybe if those shrooms would be very subtle in the dark along the little path this rock seems to trail into away from the light?! Don't let them pull away from the waterfall, that's what I'm thinking. I still love it, though!
