I've been hanging some of my older paintings around and really having a good look at them. They're not very old, maybe 2 or 3 years, but my perception of them has really changed. Being far enough removed from some of the paintings on a time scale is finally giving me a new appreciation for most of them. Even some of my old sketchbooks that I would have gladly burned upon completion are looking better as the years pass. I used to have to hide paintings from myself after completion so I wouldn't be tempted to paint over them. As I gain more experience, I look back with more fondness.
I threw out a many paintings and drawings earlier in the summer, but the paintings that I kept and admire are stepping stones for me as I continue.
