You have to draw for yourself. You have to. Even if you draw for money you still have to find the time to draw for yourself.
As far as crit goes there is a period for an artist where single image based critique doesn't really help and you are firmly there. Honestly a lot of people are because they think they can just draw and get better without ever practicing. Study anatomy. Pick an area you want to work on and focus on that (arms, hands, legs, whatever) Go on deviantart, find a stock photo account and do different types of study. Gesture. Form.
Go buy a big old cheap pad of newsprint and get some crayons and work on capturing the movement and volume of a person.
You're on the internet you have a world of free information out there to help you teach yourself. And you have to. Only you can get yourself better at art.
Youtube: Sycra, Proko Look around from there you'll find tons of people teaching and you can pick out the ones you like.
