This one I started to use the wacom tablet in photoshop - it was a bit awkward to me since I'm used to the brush behavior in Illustrator. I spent maybe 2 minutes tracing over the sketch and decided I'll go back to doing it in Illustrator for now...that way I can always scale it up later if I want. Below is a picture of the sketch and the quick trace I did in ps. I would like to go back to ps at some point because it did seem like it had a lot more options depending on how you tilted the brush.
Here's a few more quick sketches I hope to go back over
