Hello! I’ve been willing to answer you these days. Here I am. I use sometimes reference for some details. Most of the time it’s for the outfits. Poses most of the time are by intuition as soon as I start drawing but if I want something really certain I find the best and inspiring reference or I make my husband pose for me.
My advice is just lots of sketching in the mean time of various things from life. I’m having a blast drawing people in coffee shops or when I’m hanging out with friends. Keeping your hand busy most of the time helps a lot for the improvement. And using reference if needed is not a crime too :>
