I think it's great. It's more staged than the original. The differences are minor, but it seems more well thought through - the reflection is clearer and more striking, and the composition just works better with the waterline higher. That little bit of extra detail in the dark background hints at more depth and gives the image a bit of mystery. The strangely shaped artwork really grabs the eye. It's very difficult to pull off symmetry well, but I feel like you've done a great job with this.

If I had to criticize anything, it would be that the lights along the waterline are blown out and that the trees are visible enough to interfere, but not visible enough to stand out as an element unto themselves. These are pretty much factors beyond your control though, unless you want to delve into the wonderful world of multiple exposures and tonemapping
