I don't really have many fullbody shots to begin with. And while I get a bit uncomfortable, due to my own inability to draw them, I just suck it up and retry until I get a decent result. A few years back I was struggling with hands in pretty much the same way. Not saying I am great at them now, but I certainly don't hide them behind backs/hair/stuff like I used to. So during that period, a person whose art I really admire told me "either don't draw hands or just make all your characters amputees - the result will be pretty much the same, since you refuse to challenge yourself to learn" ... and then I stopped avoiding hands, even if I didn't want to. And now I apply that logic to everything I draw, no matter how much I don't want to tackle that drawing subject. I mean, trying but failing is still more experience than not trying at all =DD
