From Script to Screen: Protagonist Colour Studies

I decided to play about with some colour on my Protagonist. I want to try and keep most of the colours cool since it's in space and I'm trying to limit my colour palette. I'm leaning more towards blues since my character is meant to be clever and swift, and for me when I think of colours linked to that I think of blue. However, I also quite like the purple variations. After I narrow down the colours I'm also going to experiment with skin patterns (spots, speckles, stripes) to go on my character's face. This is also the first time I've really drawn like this so it is very new to me but I think using Illustrator is really helping me.
