I like it.
I'm hesitant to mention this because you are an excellent photographer and your images are so much better than mine, but it seems like the upper left side is just leaning a bit to the left due to perspective. I usually use the PS warp function and/or liquify for situations like this to selectively warp because, for instance, the reflections look straight but the trees and shoreline look a little slanted.
Thought I would mention there is another tool in PS that I like to use in addition to what you mentioned, and that would be under filter >>> adaptive wide angle.
There are several videos's on this at utube , but I especially like Jimmy McIntyre's
