Posing tip
Loads of people ask me about posing guide books. And although it might work for some situations I do strongly believe that everyone is unique and has their own poses that work.
Plus I like to play a bit with more funky poses 😉 so don’t limit yourself but experiment with curves. Find nice lines and motion.
Also giving a model a prop can work wonders. Often arms and hands are very difficult especially with starting models. Giving them something to hold/play with really makes it easier.
Good luck
