this sounds odd, but worked for me, try holding youy pencil/pen with the opposite hand and placing it over your drawings, and try making a sketche (got something to do with the oposite sides of the brain).
At least with me I started noticing my "bad proportions" all of a sudden.
Or try drawing a "preview" in small scales before you do draw the real thing, small like in a papper's corner.
perfect drawing!
I hate you... becuase I can't ever get porportions right..
But I love all of your work!
