Thank you, Crystal!
Faisal, I always watermark my paintings when I post them online as I've had stuff "stolen" and try to thwart future thievery by watermarking in a place that is noticeable. Since this forum is open to anyone who wants to visit, I advise all artists here to watermark their art as well as post only small, low resolution photos of it.
Thanks, Judy. Your tip about the green reflected light was a big help.
Thanks, Alan!
