Ahh my final Life Drawing session for the semester, so sad :(
These are scanned in order of completion as well, so the first row and the first 2 of the second row are all 1 minute sketches, then you go into longer 3 minute poses. That is the general process as well, start of which short, gesture type poses to get you warmed up and get into the longer poses.
It's also interesting with these is everything is happening so fast generally, you don't have time to sharpen your pencil, so towards the end my line work becomes really broad and soft looking which I like as well. With any Life Drawing it's better to use a softer lead like a 2B than hard lead, to get these flowing lines happening.
