Pros: 1. I was able to create a GIF animation because it was explained easily even though there were many functions I didn't know. It's a lecture focused on easy but highly useful things. 2. It was easy to develop animation sense because the teacher prepared various sources. It's a process that makes it easier to understand if you go through it before drawing each one yourself and creating an animation. Cons: 1. The video quality was not good, so I had a hard time figuring out which layer you were referring to. It would have been easier to understand if you simply explained which layer it was instead of saying 'this' or 'this' when referring to a specific layer. 2. It would have been easier if you had told me that there is a function that copies the frame you want to copy on the timeline and press Copy Frame to immediately copy it to the next frame. I found out later when I was pressing something, but I think it would have been good to use it whenever there was a scene that was repeated during class.
