I think the issue you're having is that you aren't using shapes to construct your drawings. It looks like you start by drawing the outline straight away and it's almost impossible to keep track of proportions that way. To get better at proportions you need to think of the entire drawing at the same time - you need to think about the size of the head in relation to the size of everything else all at the same time. You can't do that if you're focusing on drawing the final lines straight away.
Do very loose, very light shapes just to block in your figures or heads or whatever else you want to draw, it's easier to think of a head as an oval and a hand as a square. A bad habit I used to have was also looking really close at the part of the picture I was working on. So I'd be focusing all my attention on making an eye look good - and it would look good. But because I wasn't looking at anything else that eye would end up too big, too small or wonky - what I needed to do was look at the whole head and draw the eye as a circle. Then when that circle was the right size and in the right place I could add details to it and make it look nice.
Oh, and measure everything before you add the final lines. Even if you don't want to start with drawing shapes at least do a very very light sketch, measure it, correct anything that's wrong, then add the final lines over the top.
