Here's a recent drawing of one of my characters (her name's Terri) I usually draw.
I've seen your drawings a few times and i think you picked up a few bad habits:
-Characters doesn't have to always stay perfectly upright, especially not when they are aggravated/in conflict. I know this sounds dumb, but try out acting as if you are in battle with someone and you'll get good ideas for poses.
-Breasts are not simple ovals (even if they are big). I'm going to assume you are a guy, try to feel your chest and see where it lies and ends on your body. You don't have to be female to really guess where they are, but if you are stumped you can always look up some examples to get an idea what they look like on paper.
-Continuing on, a good way to learn anatomy is to look up pictures of people (Or just people irl), and try putting them on paper. You'll get a basic sense what a human body looks like.
-Not entirely nessecary, but try out different coloring mediums, like crayons, ink or paint(If you can afford it). You can only become so good with just plain pencil and paper. Or you can go digital.
Try picking up "Drawing on the right side of the brain" if you get the chance. I'll help you a lot
