Ultimate fighter I - step IV... Committing to a color scheme!

 The vision I had for this color pass didn't quite materialize but I seem to be getting closer to where I want to be, i.e., "colorful monochromatic" ...

 ... I used carbon black instead of turquoise phtalo by mistake... but this could be a blessing in disguise since I want my darks to be pitch black in strategic areas! I need more knife work to recuperate some color nuances and textures before I call it quit. I shied away from the idea of going more abstract since this composition is all lines and dark masses.
