I think you need to be more specfic on what you want for a critique. What course are you working on, or what do you want us to look at? When you are just beginning and just starting to develop your skills, you can quickly get overwhelmed with a thousand advices. You mentioned linework, is that what you wanted looked at? You can improve linework by starting VERY simple, just draw straight lines, place two points on the paper, and, with purpose, lay down the line, using your arm vice just your fingers or wrist (Proko has videos on this, or just google "drawing with your whole arm"). Then work on curves, and then cicles. Just lay down the line, don't get attached to accuracy or it being exactly straight or round, just work on a smooth execution. Practice it, and then do it as a warm up before you start your normal figure practice session. For the figures, I think you are looking at your paper too much and trying to get the pose "right", but you do need to start your gesture first. All of you figures are very verticle, which makes them all look kind of the same, even though they are different. Try to get a feel of the action or motion of the pose, and then exaggerate that motion before you start getting into detail. Again, Proko has a great example of this in one of the critique videos, either the figure drawing or anatomy course (its from about 8 years ago, I forget which course it was under).

A common issue with your figures is proportions, for example you're drawing the head too small compared to the body. So I'd put some time into studying those proportions, proko has some video on it, watch those videos and then do the proportions from imagination, it's really really helpful, I recently started doing that and my figures improved. As for the gesture I don't think you're too focused in the contour because you're simplifying bumps of the anatomy into simple C or S curves which is good. I think your gestures need some straights so they feel more structured. Have you watched the NMA videos of quick poses? It's better if you do these gestures on your own and then you watch the instructors do it, and then you do them again, correcting your mistakes based on the instructors input, you learn faster that way. This is the gestures you can do on your own: https://www.youtube.com/watch?v=NSvq8FaU7vA&list=PL7EWYwaF6E-H65W-hXeKvvO_xNA_kIs5w And these are the instructor examples: https://www.youtube.com/watch?v=zFP8L4OUL2E&list=PL7EWYwaF6E-GiaE31csl_6c8tlifE8Nb5
