The city. The rooftop view, light and color studies

I've been wanting to draw the incredible rooftop view from my tiny New York City 1-bedroom apartment. Or should I say sardine can?
I took some photos for detail references but this was drawn while sitting by the window.
The penciling is almost done, then the inking will happen.
After that it's a matter of studying color and light. The plan is to do three exact copies each one with a different light according to time of day, early morning, afternoon and sunset wIth a possible fourth for late night. A bit of 'a la Monet,' plein-air landscape painting.
