Hi West Ham Fan. Isn't it horrible when you don't feel happy about your hair, I've been there and know how you feel, not nice. I would imagine it's the 'shock' factor. Do you have a good friend who will give you an honest opinion? I'd give yourself a couple of weeks and if you don't like it you could have some highlights put in per your post above this one.
From how you describe yourself with the olive skin I would imagine it does look very nice and natural, esp if it's long and long term it'll probably make it better condition wise too.
