I think its because there is no challenge when you get used to it. No new ideas. Which isn't bad, that is a challenge in and of itself. But yes, after 6 months I do want to change it up. I miss painting I have no paints right now sadly.
Why not paint?
I do watercolors but rarely acrylics, Watercolor is somewhere between drawing and painting. Mine is more drawing,
I see people drawing with acrylic paints on the sketchbook or a big paper.
Just not a good time. I have limited space and materials at the moment.
I do have a limited space too. Totally.
