I am having such a problem with the sky! I repainted it today, making the green stripe and yellow area by the top of the trees less noticeable. I like what I did, but I am having a big problem with the way the paint is showing brush marks. Before, when it dried I had areas that were shiny and parts that were sunk in and dead looking. I think now the only hope for it will be retouch varnish when the painting is finished. Hopefully that will take care of those shiny/dull spots.
I do have more work to do in places on the painting, and a bit more touching up in the flowers, and a few places I missed in the sky. I hope I can get it finished by Sunday afternoon. I think I am on a roll now.
