A question I commonly get asked is "where do you get your inspiration from?"
Most of my work is emotional, and so I don't use much in the way of source material.
However when I do need some visual inspiration, I tend to take pictures of things that interest me when i'm out on a walk, or look through images of disused and abandoned buildings online and in books. I can then pick through the images and use them as a framework for my next painting.
If your feeling a little uninspired at the moment, then get yourself online or hunt through your bookshelf and see what you can find to get motivated for your next piece.
Happy hunting folks!
