The proportions of your figures look just fine. You are doing views from various angles (good). You need to do some work on hands and feet (Line of Action has a section on feet & hands). I would recommend you date your work. Why? When you look back over your works at a later date to see the progress you have made, you will have a better idea of the order of the drawings (you do not have to depend on your memory). You might want to investigate the following sites: Pinterest & On Air Video. Keep practicing because practice makes better.
