My biggest sponsor (aka my sister) got me a phone holder for my birthday back in October, and I got to test it last month.

It's sped up a lot so that it's not super long. It's really neat to see it done very fast!

But if you're interested, I've also uploaded this one in real time. They're broken into two parts: inking & painting. If it's too boring, you can also just skip down to the last video which is sped up. :)
