Here is another one (see two posts down) that left the studio over a year ago, thinking it was done, only to return and be almost completely painted over. You can see the original, which I was actually quite pleased with when I did it,
here.
However, as I continually grow and develop as an artist, I see things differently. (As an aside, I saw an interview with the painter Brice Marden once and he said something which I thought was very apropos about how each time we look at a painting the experience is different because, even though the painting hasn't changed, we have.)
This painting was at the Kada Gallery in Erie, PA for a year. I brought it back to my studio in November of last year and found that I wasn't as satisfied with it as I had thought I was. I went back and looked at the series of pastel drawings that I had done before commencing work on the original painting and found that one of the qualities that I liked about the drawings was the value contrast between the building and the sky, something that was missing from the painting. So I began to rework the painting by darkening the value of the building and adding, consequently, more color to it. This, however, caused the building to push forward and compete with the foreground so I added more value contrast and saturated greens and oranges to the foreground in order to make it advance in front of the building. I also reworked the sky, making it bluer at the top and greener closer to the horizon. Having to repaint the negative spaces between the tree branched necessitated repainting a lot of the trees in order to maintain the softer edges of wet paint meeting wet paint.
In the end, I think it's a much better painting and I'm glad that it returned to me so I could finish it.
