Well, I dove into this and made a bunch of images for Redbubble, some modified/manipulated quite a bit and some uploaded as-is or nearly so. Haven't learned anything worth sharing. I now have a collection of AI images that weren't easily marketable, so today I did a sketch with traditional media using one of those "unsuccessful" images as a loose reference. I guess maybe I should start a thread in mixed media. . . .
Haven't been here so haven't kept up with any threads.
Redbubble shop in my signature if anyone is interested. I tried a variety of styles, etc. The most recent 40ish designs are all derived from AI (except the most recent, which is traditional media with AI image as very loose reference).
Edited to add: Oops, there are some public domain images in the most recent 40ish as well. Forgot about those.
