The way you paint digitally is fascinating.
But some life drawing classes would do wonders for you.
I would suggest visiting your local arts college. most have figure drawing classes any one can attend for a small fee.
Thanks Ophelias Flower. I've taken life drawing classes for my degree in graphic design. Maybe I could take some new figure drawing classes to freshen up?
Art class is not cheap though. I've spent over 250$ on a small tool box of arts supply's and I've shopped around every small ”mom & pop” art store I could find to get the lowest prices I could find.
Here is a Portrait drawing.
most schools I know offer classes for outsiders for under ten dollars. and you could always ask if you could use digital medium in the class, you'd have to ask in advance and they may have to ask the model, but I have seen it done before.
Friends are also a great resource for gesture sketches. (unless they can hold still for a 45 minute drawing) and gesture sketches are just as important as actual drawings because it is easier to capture movement and feel in them
if you have trouble drawing what you see in front of you (many artists draw what they think things should be instead) I would suggest blind contour studies where you look at an object and draw it with out looking at the page or taking your pen off the paper. these will never look good. But they will change the way you drawl, I promise. I can't even begin to tell you how much they helpd me.
also your portrait drawing is a lot stonger than the others!
Nose structure might be something to work on though.
