My first time lapse video sketch

So I wanted to try doing a time lapse video. Clearly if you watch it, you'll see I need to work on it a bit! I was holding my phone with one hand and sketching with the other, and I need to linger on the end a bit because it abruptly cuts off. But here is a photo of the finished sketch which took probably about 5 mintues. And here is a link to see the video on my Facebook page

I will have to try it again soon!
