My personal opinion is that there is no such thing as spending to much time on module 1 or 2. These are the foundational skills that will apply to everything else you do. The better that you get at these the easier everything else will be. If you are not having fun with it, definitely move on but you can always come back. I have been doing this for a bit now and for each character I make I still do a cylinder study for. You might find that enjoyable and challenging to move to the cylinder studies over a character. Basically if you arn't having fun move to something else but always, always come back to practice the basics. In my opinion a cylinder is one of the most important fundamentals you can learn, and understanding it will come back over and over and over and over again. One thing that I would recommend when doing the cylinders over a figure is to draw the contour lines over them, this will help you understand the shape a lot more and it will be challenging I imagine. Keep up the good work! I love how you are thinking about these limbs ans cylinders!
