[OC] This is probably the best photo I've ever taken

Can we see the photo, or do we only get the one of you taking it? /s

At the very least, you should rotate the photo so that the horizon is horizontal.
- Then the subject is falling backwards. Plus, the tilt focuses the subject's view to the lower right. Lends action, what is he looking at? PLUS, levelling the horizon reduces the subject's importance.
  (Jesus, I sound like an art critic. But hell, I think the pic is near perfect.)
  
  it is not. a tilted horizon is never acceptable regardless of whatever else is going on in the photo. However the subject was standing with a flat horizon is authentic. The subject's actual stance is more interesting than the false stance that the tilting has inferred.
- Here's a rotated version, cropped as little as I can manage.
  
  Also while obviously nobody should treat compositional "rules" as actual hard-and-fast rules, I do quite like this one if it is cropped to put the person and the horizon on the thirds lines
- why?
  I've taken many photographs with non horizontal horizons. When the composition is more important than documentation, you can rotate the horizon any way you like
  
  because it feels off balance.
  the level of the horizon is a key part of composition. it effects comfort, balance, and groundedness. when the horizon is not level it will feel disorienting, dizzy, or chaotic. yes, you can break compositional rules for artistic effect, but you need to learn the rules and why they matter before you can do so effectively. the example you posted below doesn't really make your case. it's not that great of a photo, rotated or not. to intentionally rotate the horizon to give it an uncomfortable or disorienting feeling is fine if that's the goal hell, maybe it's more to feel otherworldly or any other number of things you can derive from it. the point is that you need a reason and intent behind the unlevel horizon. what feeling were you trying to invoke by not having the ground beneath the feet of the viewer?
  
  Nah, bro.
  He's right about this one.

As others have said, a really easy improvement is to straighten that horizon up so all the water doesn't tip out.

I remember my mentor told me, I forgot where its from, photography is made of two things, hours of setup for 1 good photo, and the once in a lifetime photos taken spur of the moment. Always know how to prepare and always be ready.
This is a lovely photo, best of luck on many more!
- I suck, so I only get the spur-of-the-moment shots.
  This is one of my latest favorites. Window prisms hit just right, zero adjustment.
  
  That is really cool! Seem to be doing good, hope you continue to enjoy it!

You’re just missing the spyglass

Praise Kier!

Overall nice photo. Good capture of the sky. 👍🏾
I would bright up the shadows a bit and rotate it slightly to make the horizon flat to improve it a bit more.

It's a nice photo.
- Thanks! :)

Those clouds don't seem real. They meet the horizon but my brain isn't convinced they shrink enough. Hell of a sky
