Wow!!! and Wow!!!
I would reduce some sky above the Sun. This will put horizon line in the middle and reinforce the feel of to be balance helping the Sun to command. That what I was thinking. However, the crop has changed the image more than I thought. Your photo is so Good that it is very hard to harm it even with my not very bright idea )))) I have attached the cropped attempt.
I like the photo!!! мой вариант фото
