I'm still working through the class, and already found it worthwhile to take notes. I have a hard time working loose and I usually resort to adding more and more detail, working small, fixing small imperfections, and holding the pen or brush with the well-known death grip. This can be exhausting and result in lifeless paintings that took way too long to do. It is also not very relaxing. I needed this class.
Robert's suggestions to work large, to hold the pen/brush further up and in a loose grip, and especially to omit detail and try to paint in as few strokes as possible, as well as the demonstrations, are incredibly helpful.
The tiny tabasco bottle at the top of the page in the photo below is what I drew before Robert's demonstration. This was my "loose" drawing... The bigger bottle at the bottom is what I drew after watching Robert's demonstration. This is just plain paper, not watercolor paper, but I already feel that this class has given me the guidelines and insight into painting more loosely.
I will keep watching the class and update my work here.
Thank you, Robert, for sharing what you're good at so well!
Update: Tried with a subject on plain paper (not watercolor paper) - loose sketch with pencil, then pen (holding them away from the tip and not fixing mistakes), then watercolor, then some white gouache.
I feel like it's decent for a quick try on inappropriate paper but it's bearly readable. Also it's still rather small since I'm used to working small. I might try this again on proper paper and be more patient with it (or maybe try gouache?). It was a good value study though (and a good study of getting values using color and not monochrome) and good practice.
