I guess that male legs and hands. I dunno, these parts usually bring me the most headache >.<

Hands ruin my pictures, I never get the overlappign fingers/ shapes right. I have to search for pictures of hand poses or just try hold my own hand still for a while. x]

Feet, hands, and action poses. Also animals and girls.
I'm not one to take the easy way out. I practice. I find references, and fill notebook pages with practice sketches. I figure, if you don't draw what challenges you, you'll never get better.

Of course it has to be the hands.
*Sigh*

I also have trouble with hands and feet. Though, more so with hands.
I tend to hide them so they don't mess up my whole drawing x3

hands are hardest to draw
it's dificult to get them in motion

Hands and toes are complicated because I tend to over think how intricate they should be.
I went through and art class at school that forced me to draw problem areas so it sort of forced me into being comfortable with drawing them.

When I was younger I found problems with the femine curves, as I got older I got better because of experience and chang in my own self.
Ugh puberty in other words.

Hands and feet, definitely. When it comes to shading and coloring, I have a hard time with the male abdominal muscles, especially the ones with six-pack. Shadowing and highlighting just consumed so much time and work, and so very, very difficult.

Basically, every body part is hard when you subject them in acute perspective, especially the face. Try drawing the head when you tilt it a little bit vertically. And you will know what I'm talking about.

I hate the three P's!: Perspective; Position; Proportion.
But I'm trying to learn them all...

arms D|
the angles and everything -__-;
hands and feet are bad, too, but you don't notice them as much because i normally cut them off ^^;

Now, it's the feet. x.x I'm so much better at hands now! x3

Toes and Fingers. Sometimes I have trouble drawing ears and eyes. xP
I think because they require so much detail, so they're harder. To me, anyway.
I mostly feel fustrated when I have to erase more then three times.
Or when I erase a hole through my paper. (hate it when that happens) :(

bare feet are sooo hard for me--so hard, i've just started to draw shoes on most of my characters instead of feet!

using model references has helped me a lot with this sort of thing, though :]

My least favorite is definitely feet. I'm going to have to start working on them seriously, though, if I ever want to draw a person with actual toes. xD

Actually, I've always kind of liked drawing hands. They're definitely my favorite part of any drawing, and my art teacher says I draw hands like a Renaissance artist, very delicately.

It occurs to me that ears aren't that easy either. It's really hard to make them not look like random half-ovals glued onto the side of the head.

Hands. And sometimes legs ):

the hands and feet is the hardest part to draw.

Noses :[
When attempting a realistic portrait, the nose always looks ridiculous - maybe I should find a tutorial x3

I've never tried drawing feet before;; I think I'll have a go later :]]

Hand and feet. D8

Back when I drew often, I use to always kick myself (not physically of course) because I just couldn't get the hands or feet right! I've wasted so much paper by throwing it all away after getting frustrated. My mom, back when money wasn't as much of a problem as it is now, use to buy me cheap drawing books to help me. But I just never got the hang of it.

For me the hardest parts to draw are the hands, feet, legs and small boobs.
-shot.-
:opps:

The hardest for me are hands, thighs, and arms.

I have issues with anything that is below the waist that I can't hide with a robe/dress/skirt. When I try to do pants, they look like my person is wearing spandex. Also I can't draw shoes that well so that's one thing to work on, at least I can do hands in a passable manner.

It seems that everyone has basicaly the same problem!
Hands are just so complicated to draw!

What was funny, was that when I was reading your post, I couldn't help but laugh at the comment you made about drawing the subject's hands behind there back.
I ALWAYS DO THAT! xD

I've gotten a little better with them over time, though I cant draw them too detailed.

I've always had a problem with drawing below the waist too.
My legs are always awkward looking. :(

HANDS, and arms! >.<
Thighs legs! >.<

hands, feet but knees too ^^"

i would have to say eyes ar the hardest body part there is to draw i cant draw eyes with a pincle but i can do eyes great on scratch board

No wai, hands and feet are easy peasy when you get used to them. Ears are the hardest. You don't know where to scribble them. Ever. Like, I try drawing them really realistic looking...and it comes out all awkward. I try NOT to draw them.
