Here is my updated color study! I spent some time playing with my first one in Photoshop to see how far the image needed to be pushed, and then I pushed it traditionally on the original study. After pumping up the colors and focus, as well as changing some lighting, I am much happier with moving forward.
See for yourself how it's changed below. The first version is on the left and the newer is on the right.
Unfortunately, some other projects need to come before the next stage of this piece. But I'm finally on my way to the final!
