A couple of important notes:
1.
All Procreate specific things are marked in bold
2.
Things important in general are italicised and underlined
Note the green boxes in this image, what I have done is; choose a darker colour and colour it in as a flat colou, then choose
any watercolour brush (
Watercolour —> Round Brush for Procreate) and shade lightly around the flat colour. Then shade in
jagged, thin lines over the lightly shaded area almost parallel to the flat colour. Then choose a
smudge tool, and smudge the lines so that they are not extremely pronounced.
For round surfaces, start shading in large circles and move inward in smaller concentric circles till a small bright or dark spot, as desired.
For flat or slightly curved surfaces, shade in long lines with rounded edges and move inward with lines of smaller thickness, a bright spot is generally not seen in such forms of shading, so only a slight shading is required
(as seen in the stomach of the reference).
