Good morning, friend.
Something of that nature does happen to me weeks ago, it was not about a drawing, it was about a writing piece.
What i realized was that, as I was talking, I was missing the important word's I should have included in the piece, but what saved me was that, I have to do a thorough editing of the writing.
Talking when we are doing an activity will hinder us from giving the best we could do. Yet the drawing you show us is superb, I can still see few steps, cheers.
Thanks for the insight and warm feedback.
You are welcome.
