the blue makes this picture colder then the other one. The purpleish one is more comfortable, smooth - the blue-version more sharp, alarming/awake. both versions are good Depends on what you want to convert with your photo
The blue provides a nice contrast, but maybe it's just a bit much (in my opinion). You might try using the original as a base, and put the new one as a layer over it at about 50% transparency and see how that looks.
Either way, they're both excellent pictures! I tried to take night light pictures while I was there, but mine never turned out this good!
you're welcome : ) Most of the time they have nothing helpful to say-- if they even say anything. I'm always glad to get some kind of feedback. Personally, I prefer people leaving comments to favorite-ing on my works.
