Thank you so much ! I was super hesitant as well at first but I just gave it a try. I watched a lot of tutorials on how to draw folds but nothing really helped much until I started painting. I use the default round brush with pen pressure, I start with the big folds first then I start adding more details little by little... To speed up the process, I select the areas that need to be darker using the lasso tool and copy them to another layer then adjust the brightness/contrast, in that way I can get the colors and values that I want.. (I do the same for the brighter areas)
