Here is an update for the final illustration. I decided to go with the 1st thumbnail because I wanted to show more of her wrist device. The drone took me a while before I was somewhat happy with the design. I wanted it to be low-profile, but still keeping a high-tech look.
I trying to draw the drone in a way that it looks closer to the foreground but I'm still having some trouble, lol. Also, I'm not sure if her legs are in perspective or not. It looks a little weird to me. Another thing I'm having trouble with is the background, I'm thinking about doing a cyberpunk kind of alley but I'm not too sure.
EDIT: Should I stick more to the first thumbnail and show less of her legs, or keep it as is?
