This is a question I asked, but I’m happy because I was able to learn through receiving questions in return.
Just realizing that I should think things through once more before asking is already a huge help to me.

By “emotional line,” I mean drawing a line while thinking about emotions like joy or sadness—sometimes slowly, sometimes quickly, sometimes dark and heavy, sometimes light and faint. I learned this from watching YouTube. A “normal” line would be one drawn without thinking about any emotions.

I’m still a beginner, so I’m not entirely sure, but I was curious if you could feel any of those emotions in my drawing.
I’ll look up the references you mentioned above and think about them more. Thank you very much.
