Too dark. Half of your image is so dark, it's very hard to see what is going on, or what you are trying to communicate. Particularly the RH side. The building looks like a facade, with no real back to it, the stars seem to jam right up against the lit front, with the remaining blackness on the right just "dead space."
The figures are almost impossible to make out as a couple, the light swirl is too dominant.

Beautiful concept, just too "moody," with not enough consistent illumination for the viewer to clearly appreciate your efforts.

instead of give the author such negative comment, you could give some advice to improve the image mossyb, maybe its just someone how just get started with ps and then u need some build up comments and not that kind ur give

coldplay 4ever good job

The idea is good, however the image is very dark. Its almost like the saturation and contrast are making this image darker.
With the couple in the foreground, if you took a bit of the sparkles around them off, then they would be a little bit more clearer as well, the you may not need to lighten the image too much more

Goodluck anyway author

Lovely image and great concept ... I agree it is a little dark but only a little ... I have seen a night sky where the stars stand out against a "void" when there is something that you cannot quite make out in front of them. I think a little lightening and some minor toning down of the sparkles would enhance the image .

To lighten you can apply a Levels adjustment layer and brighten it up so the image is "too" light ... then mask out what you don't want to lighten and set opacity to get it just right ...that is if you want to

EDIT: Better!

i think its fine dark... its night time with no lights really... its supposed to be dark. i wouldnt lighten it up any more... if you must go that route in one way or another, instead bring out more details at the focal points to make them more pronounced, and bring in a little more detail in the darker parts to keep it balanced.

Very very nice piece of work...best of luck author
