Yes, it’s common to do the sketch in a different color. Usually red or blue. So, pink works just as well. I think Paul actually covers this in Panels, but I’m not 100% sure on that. This is totally a valid workflow.
Instead of reducing the Lines opacity. You can adjust the onion skins opacity and/or color in the properties editor. In newer versions of Blender you can set separate colors for Keyframes before and keyframes after your current frame. With that said, if reducing the lines layer works best for you then it’s the best approach for you.
I’m terrible at drawing, but I keep practicing. I’m also looking forward to the course focused on drawing. My understanding is it’s scheduled for some time this year.
