I really like your scetches to start off! I think my only critiques would be that your proportions are a off in some places, most of the mistakes are that the and chest are short (this may be a style thing, if so, carry on, it doesn't look bad) and the other suggestion is that you should work on hands some more, some of your spacing and shapes are off. Great work though! keep at it!
I personnally think you are doing very well! I like your approach with the "bean" shape to help form the chest and torso area. My one suggestion would to work on your proportions, some of them are a litte wonky (its ok, thats one of things im really trying to improve too!) I would just suggest to take a little more time on proportions and they would improve a lot. Also, I really love the way your scetches look so clean! all the lines are very nice and "crisp" hope this helps a little!
