vLike Kinsei say

cause humor can brightened up an art's quality. The color mood is not entirely fitting for most things that are there, the sky is night and sparkles many star so most surroundings of the art suppose to be dark in the bluish side. The light flare at the background where the city is isn't giving much impact on how festive a city it appear to be in which doesn't appear to affect the characters and the tree.

You could make an excuse on the foreground being bright if there were signs of high beaming streetlights from somewhere above.

On The First Day Of Christmas

I got a really nice piece of art!

I like the humorous feel of this. The play on words was pretty nice angle to go at this.
