Folds in Clothing...
I guess, for the folds in clothing, it all depends on what kind of fabric it is, the movement of the character, the conditions of the person's surroundings, the condition of the clothing. Based on those things, try to really visualize the character's clothing and movement in your head, and when you come up with something solid, sketch it down fast. Work on your general idea until you come up with desirable folds and creases.
I could draw up some examples later. So check back in soon, k?
