some good intent with doing all the studies, some nice start to loomis and Bridgman. Your lines are a little fuzzy and uncinfident though. Draw stuff from life IN PEN OR INK. It will be really hard at first but it makes yuor makrs more decisive in the long run. I remember my old design teacher tol us we could only use pencil for presentation images and everything else including studies was to be done in something pernament.
Also please resize some of your images down a little bit in the future.
