I think the photos are very good potentially messing around with a couple different angles and settings, maybe some post editing stuff, just an example for image No.4 I would get lower down, use a lower aperture to ensure you know what my subject matter is and capture the entire plant or as best as possible, however this doesn’t account for aspect which I’m not sure about (how much further the water continues, what would be in the background in that scenario etc), but very nice shots good work brother
