start with brush from http://v3rtex.deviantart.com “fallon vintage lady”

then select leaves from source picture to start constructing the body using transform and warp tools to get the shapes you want.

once the body is done, begin building the hair and the bikini. For the hair, I built a yellow layer the shape I wanted. Then a goldish brown layer of the same shape, and then overlayed a selection of the center of one of the sunflowers from the source

I then started merging layers together to blend the body parts so they looked like they were all part of the same body. Using warp, I accented her chest so her flowers were nice and full ;) and then used the patch tool to blend the limbs all together. I did a lot of burning and dodging to give shadows and highlights to the body. Then I choose to do a color overlay on all of the layers with body parts on them, using a bright green color.
(shown with some layers hidden)

after all the shadows are added, I start shadowing on the bikini parts. Because of the merge, I have to build a new arm piece to cover over the hair layer (which were three layers, I know, but I merged them together so I could work with them singularly). Burn and dodge and color overlay that layer as well. Body is about done, minus the most important part.

THE FACE!!!
No pin up is complete without killer bedroom eyes and pouty lips. But I decided to paint this ones face. I originally thought to merge a human pinup face on to the creation, but for the playing card that I ended up doing, the cartoonish painted face seemed more fun

and then the background, which again, I choose to go a little less technical. Since I decided on the fun cartoonish look of the face, I followed suit with the background the same. First I filled a blank layer with a light blue. Using rectangular marquee, I selected a point I deemed “horizon” and filled that area with a light brown. Used filter to add noise, and checked the box for monochrome. Warped that area to give it a rolling look, and then deselected, and did the same to the bottom of the sky line so that it meets up. I added shadowing around in the sand to ground “Sunny” and then blurred the sky line.

I used cloud brushes found at http://tomqvaxy.deviantart.com/art/Chinese-Clouds-by-TOMQVAXY-104437117 for the chinese clouds and went a shade lighter for the color. I then blurred the edges so they had a softer look.

I pasted two sunflowers on the corners of the pinup so it looked like a vintage playing card.
