Drawing these proportions was quite a nice exercise I need to remember these proportions for when I’m drawing other poses as limbs tend to be shorter than the other. First attempt was on the left and on the right is a more defined sketch.
Using the measurement technique marc suggested I found it quite helpful also drawing lines across where each body part should start and end is super handy.
I can honestly say quick gesture drawing makes me want to quit drawing forever, I know overtime I’ll get better but as my skills are not strong drawing quickly is so difficult I need time to fix my mistakes and understand where I’m going wrong as opposed to worrying about how much time I have left go finish a drawing. For some reason my mind can’t grasp the concept of doing something quickly lol.
