Star Trek: The Next Generation portraits

A set of three portraits of characters from Star Trek: The Next Generation, featuring Captain Picard (Sir Patrick Stewart), Geordi La Forge (LeVar Burton) and Deanna Troi (Marina Sirtis). I wanted paint some portraits with a twist, and the twist is that my colour palette was based around the colours of the characters' Starfleet uniforms.
What do you think, does it work?
