It would probably look better if you didn't go mad with brushing the entire sig and without the text. I don't care if it's supposed to be monotone; it looks bad with only one color. Lighting is off, composition is bad, effects are dreadful and are nothing related to Christmas, and depth could use more work. The focus is decent, though.
Phil, I haven't been doing graphics much longer than you have. Unfortunately, I haven't seen you improve the past month. Perhaps you're in a slump?
Just something to consider. However, if you are in a slump, this is a horrible time to continue relying on Brushes for effects in every sig you make.
