This was done in Procreate. I used watercolour brushes from Lisa Ganz's website called AqualReal. I also used techniques from the video below. One I particularly like is using the selection tool to highlight a irregular area within a block of colour, feathering it, and adjusting its hue/saturation/brightness to give a watercolour randomness to the paint.

Thanks for this great course, Emma! I learned so much! Your feedback is also very impactful. I've painted several mushroom pieces as a result, some not so good, but they taught me what I like. These are my favourites.

Mushrooms in log with Emma's compositional advice to add something on the left...the ladybug.

Dropped the inking in this version per Emma's suggestion. Thanks!

Study before final painting. Testing composition, values and palette.
