The process for this image was quite complicated and I ended up sticking a lot of different parts together .
For example I enhanced the ribs with a layer mask of an image that had those more prominent.
The most challenging thing was the light. Because the body of John was relatively uneven I had to light and colour adjust them separately using an adjustment mask.
What was important to get a high contrast (as much as possible), and a Pink tone overall yet saturated blue jeans.
Through a new layer I then modified the border when I was done with the image.
