Blueberry Field acrylic 6"x 8"

I bought some acrylic paints at the UO trade show.  I've never painted with them before.  I was afraid to use good brushes so used two old scrubbers.  Sure enough the paint was very hard on them.  I wonder what people who paint with acrylics do.
So anyway it's pretty rough but I like the composition and colors better.  I plan to try a few more of these.
