Probably a pretty good idea to have a background of perspective under your belt if you want to do it at a more professional level. I think what's ultimately more important that proportions or even perspective for that matter is the gesture, how you make the figure move around.
I once read in a book that it's actually more useful to get the gesture down first before you concern yourself with the proportions, which you can always fix while you're still in the planning stages.
