This is beautiful, I love it! It's so detailed and deep.



Since you're asking for critique specifically, I do have one thing to mention. The highlights on the plants leave me a little bit confused as to the direction of the light source. The lightness of the sky on the right in combination with the rain and the highlights on the plants to the left give the sense of lightening in the sky. The way the whole sky feels like it is lighting up, while still being dark in the nighttime goes a long way toward making this effect and is really beautiful. However, highlights on the plants on the left detract from this a little bit. Particularly those leaves growing on/right underneath the slope of the mountain, which would be in shadow if the lightening was coming from right hand sky, deep in the background.

Stronger contrast and deeper shadows in those areas which should be facing away from the light would give the piece a more dramatic feel.
