Thank you for the class, this is the first time I tried cross hatching, I am usually not very patient ;-), but I like how this turned out.
Output: The Plan for my illustration was to create a project for this class that I can upload, so I din't need a huge canvas (2048x1536px).
Style: Try out cross hatching and some of the brushes mentioned in the class, plus include some lighting effects.
Elements: I liked the idea of a mushroom house, so I deconstructed that into a mushroom and a house and wanted to play around with proportions.
Shadows, highlights and some more texture:
