I think it's a pretty image. Your thoughts on mood and color palette came together well. And it's a great composition. Well done.
Something I've seen mentioned quite often in photography videos and tutorials is the potential distracting nature of small, incidental features on the edge of the frame. In that regard, you might consider cloning out the two small plant features along the bottom, to the left and right of the foreground plants.
To me, the subject of a landscape is often just the whole scene. It feels like that in this case, to me. However, the foreground plants are like a minor subject. In that line of thinking, I think those incidental features take away from the plants.
