Greetings, Luke, excellent progress you've got there on your Google Drive! Well, if I could and would give you some advice, then it would and should be to please, please, please, please work out the looser and exaggerated forces and gestures of 117 minutes of 2 minutes of drawn poses????? And why?????? Because, It would, could, and should make your gestures and spaces less stiffest, and even more solidest, fluidest, and spontaneous.
And another thing: "Practice on the Days That You Eat." -Daniel Coyle, The Little Book Of Talent.
Good luck from me to you, and I hope you've found these completely and totally influential, inspirational, and absolutely educational and advisory.
You have some really nice drawings, I especially liked the page with three female poses that had a simple and dark shadow. These poses could have been even stronger if the starting lines had been bigger, looser and longer. I'm not sure which are which, but on the poses that look like they are 30 or 60 seconds it looks like you are drawing too fast, trying to capture the whole pose in this short time and that the big swoops or gesture lines, suffers a bit. Try doing some short timed poses, 30 second might even be too long infact. Just put down the long swooping directional lines explaining the gesture. This means that when the time is up you will probably be looking at only two long direction lines and an oval for the head. It's a huge benefit to hold the pencil with the flat side against the paper and doing soft and long searching lines in this stage. Once you accept this simple way of expressing a pose you can then lengthen the time a bit, but still use this same type of approach. The added time will add more detail, don't rush. Good luck!
