Recently for my paintings I have been posting the orginal pencil sketch I do for the painting, a work in progress shot of the painting, and then the final over on my instagram account. Just so that people can get a sense of where I start at and where I end at since sometimes my paintings sort of mutate along the way.

I like the photos you took of your friends art. Believe me I know how difficult it can be to take good photos of things on canvas, you did a great job.
