This really looks pretty serene... simple shapes, but effective, and especially with the reflective water. Curious now, is the reflection first a copy of the city flipped around, then faded? White layer on top of it? Just interesting to know these things. :)
The gradient background works well too, and the light... reminds you it really doesn't take that advanced mechanics to make something like good, just the right combinations. The large sun, the bits of color... man. I'm impressed. The more I look at this the more the little things seem to matter. The placement's just right. The sun setting into the ocean. The way the two curves overlap, the somewhat darker color tone to everything that makes it both dreamy but somewhat realistic...
This is really pretty good...
