Shape breakdown and my first time drawing animals. Holy crap I didn't know I could do this using shapes. I'm so freaking happy!!

Hello! This is my first time doing gesture drawings. The reference pictures are from lineofaction.com. These are 2 minute gesture drawings made after doing 50 or so. I want to make sure I'm on the right track. I'm finding myself run out of time before the 2 minutes are up. I'm using a chalk pen on clip studio paint. Do you prefer learning with pressure sensitivity or not? Do you work traditionally or digitally? Thanks!
