Thanks so much for the feedback. I do need to revisit some of those edges. As far as integrating the color goes, it looks like maybe I've got to figure out what the colors ought to be first

Thanks so much for the feedback, I really appreciate your taking the time to share your thoughts! Your points on color and color theme and needing to integrate the colors are well taken. It seems to be something I'm struggling with lately, and haven't got quite figured out.... at least I'm not getting it figured out before getting myself into a mess, these days.
I'm attaching below a glare-free photo of the painting as it is currently, and a paint shop pro altered version with the dress turned a dull burgundy wine-color (The dress she actually wore was a deep blue purple that I'd pushed more towards the blue) .... I'm wondering if this would work, rather than putting her in black?
