Painting with Acrylics

The middle painting was my first attempt with acrylics. I found it bland because there wasn't much of a contrast between the paints and the background. So the second painting, the one above, and I was a bit happier with the results. Of course, it seems busy, but it is what it is. I should have called it clubs, Bastones, like in Spanish cards. Finally yesterday I saw some pictures of the Northern Lights but I need to work on the background to make it look darker. We'll see how it develops.
