Hi Liam,
What a gorgeous sunrise… and the sort of morning that I would probably prefer to be out in the kayak rather than standing on the beach making the photo!
There is not a lot to grumble about this photo… perhaps my only two concerns would be the placement of the horizon line being rather low in the frame and also the paddler who is rather close to the left edge of the frame.
Almost by default, I would normally place the horizon line on the lower third of the picture and then place the paddler on the left third but like any guidelines of design, they should just be a starting point and not a hard and fast rule.
By placing the paddler close to the corner of the frame I feel that you have created some tension. Now, because this is your photo, it is really your decision as to whether you think you want this tension. I'll leave that decision to you!
Cheers, Anthony
