this is weird answer but, do you have the colors clear in your mind when you do this studies, or you go first with black and white, or gray drawings and then try looking some color schemes, love your work and how you use color!!!
Very nice designs! I like the one you chose- Pomme- though I wouldn't be too opposed to dressing like the second lady myself. It looks like nice, comfy lay-around-the-house sort of outfit. Also in my favourite colours.
