Life Drawings (CRITIQUE PLEASE)

Ok so here is some of my later life drawings from the end of the last semester. (please critique these drawings) I was hoping to have some to show from last week too but due to being sick and knowing I wouldn't be in the right mind set for life drawing I chose not to go. Although I went tonight and my drawings were pure crap but hopefully this will change by the end of next week. Anyway here they are! and again, critiques.. PLEASE! I really need to learn how to make these drawings even simpler and improve on my lineweight. (and well anything else you can see I may need improvements on)



that is one looong femur :S


really wish i had drawn this 3 minute more in the center of the page :S






the one below is a 1 minute







i didn't write down the times of the first two on the page but they were both 3 minute poses. unfortunantly for this top pose i had to try and squeeze the head in there and as you can see it obviously didn't work.





the one below is a 30 second pose.
