Speedpaint battle art

The art was created for weekly challendge and took about 3 hours from idea to final retouch. The theme was "Abandoned house" and I choose to paint the old sanatorium in the forest.
And Halloween is near, so some mistic light in the windows will make picture more interesting.

I use textures from 3dtotal mostly, but there are more interesting sites with free photos. So there is the photobash of different buildings and plants to save my time
