Weird question for drawing and youtube

So, I've been practicing for awhile now. I usually make Time Lapse videos of my drawings. Of course, I use them to visual show my improvements over time. Had a random question in my head regarding these images. Say if I had the chance to be monetized on youtube drawing from the photos from line of action and making my drawings into time lapses, would I be breaching copy right laws? I'm assuming yes but, wanted to ask.
