Serenity screencap study

[ZombieChinchilla]

Hey, guys! I'd really appreciate some crits on a study I attempted. I really need to practice with color, considering I can only really draw people during the day time and such. So I wanted to use screencaps as a study for different lighting and color and stuff. I started with this screencap of Wash from Serenity, but it didn't work out that much, to say the least. Instead of looking like there's a blue light shining on his face, it just looks like he has some weird disease. Help?





I know there's a few things wrong with his face, and I could change the proportions on some things, but I was focusing more on the colors. I also kind of just slapped the background together in two minutes, should I maybe have spent more time on it?

Please and thank you!
