Part of a personal project I'm working on right now, to experiment with unfamiliar art styles and practice lettering skills by drawing animals. I enjoyed this foray into digital mosaic (or fauxsaic as I've seen it called).
I used an online program called "Sketchpad" if you'd like to use the web tool I used for the trees. I was overall just messing around with it, but I'm very happy with the result.
One of my oldest mascots/toonsonas, a combination of "Spongebob Squarepants" and Miles "Tails" Prower. As a bonus, here's a link to the drawing video. https://www.youtube.com/watch?v=2YVxpfnwCEA&t=237s
