I went ahead and made changes. This image is not dark on my computer screen or on any other screen I have viewed it on. It is how the painting is. The original painting sold but I ordered a beautiful print on Sommerset Velvet. It printed a little darker than what I see on the screen and is more vivid in color. I thought that that was just a Sommerset Velvet characteristic. I am a lot pickier than the average consumer, which is why I ended my listings on Zazzle. But the FAA print is very nice! I hope my editing has saved it, but if not I will try to change the size to a smaller printable size for FAA.
I used to have a large format printer and printed some large prints on canvas and paper. Let me tell you, that took more skill to get those prints right than to create any artwork. I can appreciate what happens on their end. It can be very frustrating and difficult!
Thanks!
