The high key version is interesting, but I prefer the version with water that is a bit more water-colored. I like Randy's version with the slightly bluer water, and also it seems as if in this one the edges are a little more comfortable. Of course it's hard to evaluate downsampled JPG images on the net, and the very nature of the photographs is a factor, but Randy's version looks a little smoother at the transition between subject and background.
edit to add: thinking about this, I also suspect it could look a good bit different depending on how it's printed and framed. I would not write off the high key version as a matted print where its resemblance to a non-photographic graphic might be rather striking, especially the third example.
