Sometimes you have to change things up a little. It can be something as simple as doing Plein Air instead of staying in the studio or changing your medium. Change can be scary, it is safe to stay with what you are good at or know but change can be good. If you remember that it is only paint and don't take it too seriously it can be fun.
This is an abstract using acrylics. I like acrylics when doing a more free form painting because you can thin it and it has a flow to it. Also the colors can be very rich. Acrylics dry quickly so you have to paint fast which can be very freeing.
This painting reminds me of the Southwest and I have no idea why but that is what I think of when I look at it. That is the fun of abstract it can be anything to anyone.
