What was your purpose in dividing this up this way? What does each piece show us? Why is this better than showing a single frame? It's a beautiful picture, but the triptych format isn't adding anything for me, and is definitely detracting (again, for me).
Lovely image but the framing technique you have used has not worked. You can see the image through a lot of areas and it's uneven in a few areas which is very distracting. Nice lighting though.
Not sure what's going on with the frame - it's lost a few bits around the edge and in other places, but the photograph is excellently presented in this triptych.
The right hand panel has something weird about it. (The border is missing in a spot?) I'm also not sure about dividing the landscape vertically this way. There's no real natural "break points". Horizontally you could divide the water from the land and the land from the sky.
