I've been trying to think about how to go about separating the planes through the colors, and it's been difficult. (Mainly because one of my biggest weaknesses at the moment is color, haa)
I tried to make the foreground the most saturated > midground > background, although since the background is the sky, it'd be a nicer blue since it's the sky itself?
Thanks for the help and for the video! I was mainly lookin' around the color section but found the composition tag just now, so I'll have to look over those tomorrow.
Of course, here are some more updated WIPs.

and back-shadow vs front-shadow (her skin also makes for good focus)


I thought the second image would be more interesting to draw. I'll look at it again tomorrow to see which one's better to look at, I suppose.
