Eh...
The anatomy is really off. It's EVERYWHERE, and it's just not minor little flaws, it's very apparent. Firstly her calves are a bit to long, oh her thighs are too short. The left arm (her right actually) is long than the right arm (her left). The hand is...all sorts of wrong really. Mainly thanks to the index finger. Collar is too high as well.
Lastly, the colors aren't really that welcoming. Mainly in the background. The tree doesn't even have that much effort put into it, and I know people can get pretty lazy on background, but if you are at least blur it. This will take the focus off of it. The presents perspectives are WAAAY of. They're not even perfect cubes.
I could go on, but I'm sure you go the idea by now.
Hope you had a happy holidays.
