Proportions only really matter at lesson 6 and 7, in the case of lesson 5 you should focus more on making the construction as solid as possible. That way even if you drew the head a little too big or the body a little smaller etc. it will still look fine as long as it's been constructed properly. If you focus too much on proportions you will not get the same value from the exercise as you would be too worried trying to make it look good.
