Concept: Futuristic City

So this one is from my today's daily sketch session .
I want to show an other futuristic cityscape.
Lately I got a lot of blues in my palettes, therefore I tried some toxic greens.

Ususally I start with linesketching, but this one worked without lineart. I blocked in the basic shapes in Photoshop and switched over to Painter.

Critiques and comments are very welcome!
Thanks for viewing.
