Thanks wk28! I was in class mode so I'm not quite sure exactly the times, but if I'm remembering correctly the ones on the first page are 1-2 mins while the next page is around 4-5 minutes. I will definitely try to loosen up a little while drawing! I do usually have not clean sketches, and sometimes I try to make it neater after by outlining the more important parts with ink pens and then erasing the original pencil, but it is definitely something I want to work to improve on!
Thank you so much for your advice/critique!
