99 colours?! Hey man, I may not be any great when it comes to pixelart, but I know that the palette is a tad bit overkill... Great piece though! :)

Your pallete seems a little extreme to my opinion, always need to try to control that a little better, out of the 100 in there(I checked, and there were 100, not 99) ALWAYS consider using one of your current colours before you go using a new one. That and, on pixeljoint you don't need to resize your canvas to make it bigger because we already have a zoom button. Other than those minor boo boo's, I love the warm feeling towards this great christmas piece.
