I was attracted by the dramatic sky in this photo, a strong point. What I also love is the green tone in the foreground and the grey-blue in the back.
Perhaps it is my monitor but I find the photo lacking in light. I would the greens more bright, making the photo more vivid.
To my idea the composition could be improved. The left side is now quite heavy due to the low light in the mountain at the back which also comes back in the reflection. Shifting the 'volcano' to the left would give more balance I assume.
Still a strong photo. I am curious what would be your reaction.
