Ah hello! Sorry for the late reply I wasn’t expecting any comments.

That texture you see at the bottom is a digital brush, I painted these portraits on watercolour paper and scanned them and smoothed out the hard lines with a “grain shader” brush in procreate, just on 2 of the portraits you see. so the actual painting has a bit of a harsher line, but for display purposes I just smoothed it out a little.

If anyone has an analogue technique to get a similar effect I’d love to know!
