An interesting challenge, I learned a new trick. I took a slightly different approach using the dividers, I used it on the picture of the parrot only. The photo was much bigger when I started. Then I added the background and his parrot friend. Also used the free app PicSketch to create the sketch. It's basic, but easy to use and creates a decent sketch.
Paper from the Posh collage, frame and artsy bits from May 2013. Made a page divider by stretching a Lavender Treasure mask. Foliage and parrot illustrations from the New York Public Libray digital database.
Thanks for looking.
