Then why do you start drawing a face so elaboratly? It makes no sense at all.
If you wanna practice hair I suggest you just use a faceless ball and put hair on that, like you see in wig shops etc.
And I really do also suggest you practice facial anatomy too. Why do you only want to learn how to draw hair?
Being able to draw a face is much more important then hair.
And another thing: Of course it can be wrong if you trace it. Tracing gets you the lines, but you can still go wrong very easilly on the volumes.
And what's worse: If you wanna focus on the hair, SAY THAT YOU WANT TO!
Ryuamaru's been wasting his time trying to help you out and you say you don't give a rats ass? Way to go man.
Also, I took a look at your site.
You might wanna consider actually making your text a good read.
The zero punctuation idea works good for that game reviewer but it doesn't work for you. Especially if you wanna use it as portfolio, it looks really unproffesional.
Anyway I suggest you fix up your attitude.
