I personally have a hard time with hands as well. But I think what's kinda hard is when you're drawing legs. > 3<;;;

Legs are long and lanky and stuff, right? And I have a couple wrist problems, so when I draw straight lines, my wrist tends to crack -- then I have this ugly dent. D:

I usually do find ways to fix it though. One of my laziest fixes are erasing the edge that's popping out and then just filling in the line. But then -- if I'm inking with real ink, I'm kinda screwed. The only thing I can do when I ink is make the line thicker -- and all the other lines around it as well. It's really annoying, my wrist likes to get in the way when I draw. D:

I think drawing crotches are hard to draw as well. XD I remember when I was just a beginner, I actually avoided drawing them. And then when I learned that I should draw them, they were these -- awkward angles. XD They looked like they just got wedgie-ed~
