This is the cutest thing I believe I have ever seen! The colors you chose for the lights on the deer and the way they glow is a really great addition to the deer! The little tuft of hair is very cute, and almost everything about it is sparkly and perfect for the New Year!!!
The only negative things that I have to say:
I don't really get an indication of the face because the purple and blue are just a tad too dark. I am not suggesting that you change it, however, because I think that if they were any lighter, it would drown out the effect of the lights.
The antlers on the level 150 deer are not true to nature, and should have a few more points. Now I know that this isn't supposed to be TRUE TO NATURE IN EVERY WAY like a lot of people would say, but they do need to have a little resemblance to real antlers.
Anything other than those two things is perfect, and I especially like the way that you drew the hooves on the adult deer. This is a perfect adoptable, and if I had a Squiby, I would totally adopt it!
For vision I gave a five, because the vision of the lights is so pwetty! The sparkles coming from the deer's antlers are so cute, and I think this is a great visual drawing.
For originality, I gave a four-and-a-half, simply because plenty of people did New Years creatures, however this is very different from a lot of them!
For technique, I gave a five, because the lines are smooth, there aren't any out-of-the-line places except for the lights glowing, and the eyes are well done, and simply because you are amazing when it comes to spiffiness.
For impact I gave a five, because the lights contrasting on the dark colors really does make an impact, and the sparkles everywhere help add to that impact.
All in all it is a very good piece, and could only use a bit of minor adjusting. It is a wonderful little adoptable, and it is so cute and I want it so much now! lD Great work!
