S.O.S (Not really….)

Well, here’s my situation… I’ve been drawing for a very long time; however, I have absolutely no knowledge of human body structure or anatomy. I usually draw by looking at a drawing, and redrawing it with my own design. To make a long story short, does anyone have any suggestions on how I may fix this? If I actually get any responses….. Thanks in advance!
