Do it if you want to, I don't think people should seek validation since everyone has their opinions. I personally wouldn't go skin bald since it can look awkward growing back. You can also braid the side of your hair if you want a similar look without shaving :)
I think it looks pretty rad. The only issue with it is that it's been in for awhile now and starting to fade out. If you have long hair and no intention of cutting it, You won't be able to wear your hair up for quite a while when you decide to grow it back out. If you are willing to cut all of your hair short once you decide to change styles then I would say go for it! =)
I think it shows she has confidence, which is attractive, and it also has the advantage that it's a hairstyle you don't see often, but I think the hairstyle is not something a woman should go for unless she's simply looking for publicity. She still looks good because the hair she does have is very healthy, she has a great complex, and is lean and in shape, but she's not giving off the impression she's very stable or relationship material.
If a woman is looking to attract the kind of guy she wants a relationship she should stick to normal hairstyles. Traditional hairstyles are traditional for a reason, they work. On the other hand, if you're looking to do something to get you some attention for a one night stand or a short fling, then this might work.
I hate it. Where is the deceny in that? Simple and natural is always best. She would look even prettier if half of her head wasn't shaved. It doesn't look cool and is definitely not attractive, in my opinion at least.
