I chose a photo of a gorilla on google images. Did not desaturate it. Work from the colored photo, trying to use the squinting trick.

Then drawing with a blue pencil. And inking with normal writing ink and a synthetic brush. I found it difficult to get the tip really thin. Also I would have appreciated to get a slower video of your inking process.. Nevertheless  I fully enjoyed your class and learnt a lot. Just need to practice now ! Thank you so much for this concise and efficient class !Gorilla - image 2 - student project
