Just relax tonight

Vision (3):
Good use of the skyline, the body of water and the tree for foreground interest.

Originality (2.5):
There are a of silhouette photos out there, personally I really like them, but there are still a lot of them; As above though with the use of foreground interest.

Technique (3):
Overall there are good colours shown in the photo, but there is over-exposure towards the middle of the sky; perhaps a shorter exposure or or by changing the exposure value (EV).

Impact (3.5):
You have captured some really beautiful colours, I'd like to see more of the blue/purple towards the top right of the frame.
