Under The Miseltoe

If I remember well this was my first HP fanart in this style posted at Artisticalley. I was out of my mind when I saw it was commented and I realised that my previous things weren't unpopular because the depicted caracthers were so, but because they were all shit... I mean more shit than my present stuff.
Hmm, do you think I should do something with the colors? Somehow this white and green and blue shade makes the pic freeze, or does it not?
