As much as it pains me to actually ask this, and as perilously close as this brings me to actually completing a collegiate assignemt why I've been signing myself up for studio art classes I'll never know,
Would anyone be willing to sit for me so I can attempt some portrait sketches? Location, pose, and state of dress or undress is up to the client. You can keep it if you like it.
I would simply ask my friends and not bother the rest of you, but it would be better to practice on faces I'm not quite so intimately familiar with.
