The coloring book page I used is here.
I used this painting by W. Bouguereau as my inspiration for the colors.
It was just a fun exercise, about 2-3 hours, you can actually watch the video of me painting this if you'd like! It's on my livestream channel: http://www.livestream.com/katiedesousa
2-3 hours I think.
(it isn't refined because it was just a little fun speedy painting thing)
P.S. Today I found some nice wooden art panels! I bought 2, a 12x16 and a 11x14. I've just finished gessoing the 11x14 and then I'm going to sand it down super smooth and see if I can plan something to paint on it!! :)
