Hello.
I just signed up also, but I am actually returning to this field after being out of it several decades. For me, I share your sense of being overwhelmed - so I'm taking it step by step and also peeking at other courses that I'm interested in taking up later.
I was in a BFA, however, I ran out of financial aid - and hope to one day return.
The first course I selected was Inking - started back on the fundamentals. And it's something I have not done in about 3 decades (yes 30 years). I am enjoying the course, doing the exercises and some of it is coming back to me. I actually ordered the old fashioned feather quill and ink in the bottle - and will be using these once I get a bit more confident.
Welcome and hope to see some of your work here. 🙂
