Well for one thing, it looks like his head is turned at a 3/4 angle, but his face is almost dead straight, save for his nose, which is also around 3/4. And that difference throws everything else off.
Anyway, about the hair- instead of reversing your lines to create points in it, try to create those points by going in the same direction, keeping in mind how hair actually falls and what it looks like from the angle you're going for, and that in Link's case, since his hat sits fairly far back on his head, he has more hair than just the front falling about.
Using Creepy Link for an example:
Red is what would be "popping out" of his hat, or sticking up as straight hair often does in the front. Blue is what lays flat, or flatter, pressed down by the hat. And green is his sideburn things, which at a 3/4 angle, you really would only see one of unless they're either particularly long (like Creepy Link's) or swept forward, in which case you still wouldn't see much of the one on the other side of his head. And all of his hair is drawn in relatively sweeping lines going in whichever direction each part of his hair is supposed to go. Doing this, you should get less triangle clusters or "chunks" and a closer to natural look.
So I guess that's the technique suggestion, and my other point is to take consideration of where things are supposed to be in relation to other things (in this case, hairline in relation to hat, and both in relation to hair). Also practice, of course.
