This painting is also a member of the Chubby series, which mean sthat it's based on a vintage photograph. The cool thing is that this actually a photo of my grandmother!
Here's the painting after one session:
I have a general wash of an orangey redish brown, and put in some highlights and shadows with a shade of purple. Not sure what the final color scheme is going to be.
Unfortunately, I can't find my reference photo on my computer which means my husband probably jumped on my computer for some reason and closed everything without saving. I'll have to rescan and post it when I can. Enjoy!
