Abstract cityscape in progress

I've been working on about 10 pieces at once lately and not finishing many but I guess that's because I'm working through some ideas and experimenting a little. Many of my cityscape paintings start out as loose abstracts and then evolve into more representative cityscape images. As I'm working on some large pieces recently, I'm trying to keep some of the original under layers visible and let the layers overlap.

The ideas I'm playing with are the impermanence of architecture and cities constantly changing. Things are in flux - bringing a more abstract quality to areas of the paintings where an older building may have existed and are being replaced by newer structures.
