Now I think of it, rather than picking at little bits that you need to fix, I will give you some general pointers:

Leave your drawing to "rest" a bit after you've done the sketch / structuring / whatever. Get up and make a sandwich or a cup of tea or something, then come back and look at it fresh. You'll probably notice more problems that way

Also:
flip your canvas. If you flip everything horizontally it's like looking at a new picture almost, so you'll spot errors again. Flip, fix errors, flip again, fix errors, etc etc.
