Learning More in Adobe Illustrator

I got back to doing more drawing practice on my Wacom Tablet in Adobe Illustrator this evening, but this time I’m using images of pixel-based road sign silhouettes and trace them into vector-based ones so I can make patterns with them:

I’ve also been using other tools that resize, rotate and even reflect the pictures that I traced. So far I’ve been doing good on using my drawing tablet on Illustrator but I still need to watch more Illustrator videos so that I can learn more.
