Whilst this is certainly a [retty sunset, I don't fiond anything in it to particularly require the use of three frames, and, after all, it remains simply a sunset shot: not uncommon, not special, not particularly different. The tonality is good, the focus is good, and technically otherwise it's fine - but it's just a sunset, no?
How does the division of your picture into three frames enhance the photo? How does this "tell...a story or illustrates a concept or object" better than the original image?
Great colours. This is one of those photos that really doesn't benefit from the triptych treatment. Not that it really takes away from it, but there are other submissions of equal or lesser photos that put the effect to good use, and have greater impact for it.
