Sooooo this layout was "in the works" for about 3 months...because I dropped it after burning out on the painting part...ugh. Took SO long! But now it's mostly done, so I'm just gonna post it :)
I still need to work on the shading for the chest in the foreground, and maybe mess with the colors to unify it some more, but forget that for now. I'm done.
I slapped on an adjustment layer to boost the blue in all the shadows, to bring the colors together. Then I did a perfunctory pass with a mask to desaturate all the areas except the focal point. Done. Cheeeaaah!
