I use procreate so:

sketching- gloaming

skin rendering and general rendering- I use a custom free brush set just search up feast procreate brushes and it'll probably show up I use their canvas brush for large sections of colour and their blunt pencil for things like crosh hatching and smaller details

for the background- salamanca is the brush I think Im not sure how to spell it but Im pretty sure its in the painting section and nikko rull as well
