I think it is actually very nice christmas make up! I get why you would call it funny; a tree sticking out of the corner of your eye. that is certainly an interesting idea. haha.
YOu certainly used christmas colour sto inspire you, hence the red and green. That red and green really make that blue eye pop, for one thing. I dont' know if you were goign for that or not but it is an effective creation.
Connectin the red strip of the tree garland to the eye was a good call too! It kept it all connected and not separated, per se. tHe light coloured eye shadow adds that nice white light feeling of christmas, but also suggests the fresh brisk feeling of winter. It looks nice rather than having a dark colour instead.
I lvo ehow you have put the jewels on teh tree instead of maybe putting them on with eye liner or somethign like that. It makes ht ewhoel composition pop out and adds alot of interest!
For a funny Christmas Make up creation, it's a really well done christmas make up. Very pretty too!
