Depends on the size but usually a few hours if doing it on my own time. If with a model than I'll speed it up of course. No, I don't use pastelmat. I've actually never used a pastel paper before because they are too textured for me.
Beautiful! Just stumbled upon this - you have yourself a subscriber. I realize we have a lot of mutuals on Instagram - maybe we can collab? I'm a figure model!
