Note the "color lookup" layer that is clipped to my art group.
Try applying some of the color-lookup preset filters on your own art! It's a nicely subtle way to tie together the colors in a painting- especially with lots of colors.
In my painting here, I turned it down to 66%, as to not over-saturate my colors too much.
This painting still has a long way to go!
I try to work as non-destructively as possible, so I will be sifting through my established layers and cleaning up shapes, and probably introducing larger and rounder brushstrokes for more of a "painted" vibe.
Stick around- I'll eventually cover layer management and organization in my workflow!
