Maritacas in a cave near Cuiabá - MT, Brasil. Canon EOS R with a 75-300mm

If you're going to vote 2 stars or less, could you kindly comment what it is about the image that needs work or that you don't like? Is it sharpness, color or composition? Could I improve the editing or is it a capture issue? I'd really appreciate the feedback and the perspective of everyone and it is one of the reasons I want to be part of the community.

Thank you!
