Thanks for the comments guys.
I kept the horizon where it was because it lined up with the upper third of the picture, and for me, the colors and openness of the water was what I wanted to focus on more than the sky. I have been playing around with it and trying it as more of a panoramic crop too though. Very undecided in this one haha
The light beams in the sky are not faked, and the coloring was barely altered, but I will be playing around with this as well to see which tones tend to look best.
I'm looking at printing this possibly as a 20x30 or if I go panoramic at maybe a 12x36. Also not sure if I want it on paper, canvas, or possibly even metal. I've been wanting to try canvas, but I feel like the colors wouldn't be captured as well as on the other mediums.
