You've read 1984? Well, "IGNORANCE IS POWER."
Nah, I don't know how to tell you how to create eyes and arms. With arms, I have problems myself. Eyes, on 32x64 characters, I create like this:
top: 3 brown/grey pixels (eyebrows)
below: 3 white pixels
below: 1 white pixel, 1 black pixel
below: 3 white pixels
If character has angry eyes, just twist the eyebrows. This is not the most real method (eyes take out large part of face), but at least it looks like eyes in neutral pose (character doesn't look sad, angry or happy)
