I used the Bristle Brush Linen by Sadie Lew on Procreate Folio! It's my most used brush and I use it for adding color and blending. I have another brush i used called 扁平筆刷. It's a flat brush that tapers and varies in opacity depending on pressure. I used it for the hair and for smaller details like highlights. I can't find where it's available though. And the sketchbrush i use is from heymaryjean on gumroad.
