Do you base these drawings off certain people, or is this all from your head?

This and "A Pretty Face" look like some posters from movies from the 80-90. Maybe even in 60-70

Beyond amazing dude...but the stringed hair is a bit too sharp, maybe tone it down so we can appreciate the overall aura of the artwork.

This is really beautiful.

I like the subtlety of the dress and it blending off into the background, as well as the double lighting. Something strange with face/hair though. Maybe removing the dark part on top left would give more focus on the face. Or even moving it to the top right...
