Apologies for the second post but i cant edit my first... im just wondering if her hair is meant to cut off on the right side like it does. It kinda looks chopped out. Thanks. ^^

Nice~
But Yuki looks kind of...scared? Sort of.
I think it's the eyes.
And I agree with jubjub, some of the edges do looks a bit rough.
And as for Yuki's hair, don't just end it where it goes behind Kaname's back, curve it so that it looks like it's going behind his back.

But awesome job!

Overall, good vector! The room looks quite royal. Oh, haha, I noticed that there is moonlight on the floor. The room is too bright for the light of the moon to be shining through!

Their hair look really good with the minimal outlines, but I think the characters would look a lot more solid and less flat if their skin and his jacket had more long outlines, or more so if those areas were completely outlined. And I think if the characters have thin + minimal outlines, the background should be the same. In this case, I'm just talking about the curtains. They look a bit thick compared to the characters. The shininess of the curtains is kind of taking attention away from the characters too, hehe.

Now this is entirely my opinion, but I think the scene is boring. Despite the detail, the two are just standing there staring at us. In the original scan, they fill the space nicely and since they are big relative to the empty background, I focus on the emotion of the characters, but now that they're in a room and there is a lot of space, the characters lose their effect on me. When I'm viewing the full size, all I can see in my browser is their head to their bust and the window with a little bit of curtain. I think that looks a lot more interesting because the characters are big and their faces are speaking to me again. I think I sound creepy X)
