Yuki the Hedgehog Ref and Bio [UPDATED]

Well, I've gotten this done with. I've come out with an updated version of my ref/bio for my OC Yuki. I did this now for to see so he can do my request.
As you may have noticed, I have given Yuki a bit of a makeover just now. Differences include the addition of bangs, differently coloured shirt and pants, new necklace design, and three cute little freckles on the left side of his cheeck. I like those freckles. And yes, I will do an updated version on Kaori's too.
Anyways, onto the bio...
