When I feel like painting but don't know what to paint, I've learned to start painting in a series. I think its great to focus on one subject or theme and do several paintings of that subject. Some really prolific artists have even had a couple of series going at the same time.
This is the beginning of a series of paintings of women; not necessarily "femme fatales," but those that have kind of an elegance or mystery about them. I'm keeping them small for now so I can explore crops and color and then will grid them up to larger pieces.
For those of us who are all over the place with artwork, this is a great way to get a cohesive body of work. But, as importantly, the "What shall I paint today?" blues will become a thing of the past.
