One thing that can greatly improve an artists work,and confidence level is getting outside to draw, sketch, or paint. Weekly, I try to get out and about with my local urban sketching group. We find various locations and we either paint, or draw on site.
I found it so intimidating at first to sketch in public (I still get a little anxious if there are lots of people around!), but I find because there’s a group of us it gives me more confidence.
I have a few kits that i choose to take out with me depending on the location.
