I have also only started this journey, I agree that it's challenging and I believe you've answered yourself on previous post. It does seem that contour is being the main problem. I would also point out in a constructive way obviously, that you are using too many strokes to form a line, I would advise to try and do just one line even if it's not perfect but just so you train your brain to get used to do it. My gesture drawings are way far from where I want them to be but I'm just thinking of movement and not contour, sticking to the CSI rule. I will stay on gesture drawing until satisfied before moving on to the bean.
