Life drawing second year

This is the first batch of life drawings I did the first part of the year. I hope i am improving, but i still find hard to draw right all the time. I could say I haven't found my technique yet...sometimes I really enjoy the sessions, like the one with ink (GOSH I REALLY LIKE INK AND BRUSHES) other times I struggle so  hard i can't enjoy at all. So far portraits are my favorite, and i still have some issues with proportions: drawing big is quite complicated but I bet it helps big time.
