The one thing that will improve your acrylic painting skills is daily practice. It doesn’t have to be an hour or more. If you can only paint for 15 minutes, do it. Your skills will improve dramatically if you are consistent with your practice. I truly believe that painting 15 - 30 minutes per day is better than painting 2 hours on one day during the week.
I’ve been painting for years and I have seen the results myself. When I take too much time off from painting, it takes several days for my skills to come back to me.
