I loved the class. I use a similar technique and had a tracing in my sketchbook forever, so I decided to use it for this class. I like to trace the outline of the image and draw shapes over that. The class definitely had me using the pencil tool more than usual.
I enjoyed the process and learned a few new things!
Here is the link to the short video of the different phases: https://youtu.be/lr9ArVmygzM
UPDATE: I added the noise texture, love it.
I also had a new idea, I got the leopards on Creative Market and had to do something with them, here it is.
