I didn't think this was half bad. Like the guy above me (or below me, I dunno how these critiques get stacked, since I don't do enough of them) I thought the length was just about right. I loved the fire effects animation and how you managed the lighting during the fire sequence, but I'm wondering what your fire would look like if you made it look a little brighter, like if you added a more yellow-ish orange tone to it, just a bit.

Another thing you could try is for stuff like in the opening establishing shot, you had the camera truck into the door of the house. I noticed that the snowman is part of the background you're trucking to. You could make that kind of shot more immersive if you had the snowman on a separate layer and moving away from the center while getting bigger, sort of like the camera has to go forward and past the snowman. It'd help to bring the audience in.

There's also one instance where after the boys open the presents, Edd's mouth corner comes off his face. Not terrible, but it's something that made me stare at it for a bit and miss the joke for Tom's face not changing.

Also, when Edd first runs to the living room, the wall sliding by is a bit of a throw-off. I think it needs a cushioning. Maybe a good ease-out. It'd look much better.

On top of that, when you're going to have a close-up shot, like the base of the tree when close-up on the presents, it helps to add more detail. I'm talking about the tree here, the presents look fine. The tree is... okay, but could use a bit of work, but not too much work, or you'll take too much attention away from the presents. This is another case where I stared away from the main focus. I think in this case, if you gave the tree a bit of a scribbly shading for the needles, it'd look much better without taking a ton of attention away from the presents.

All that said, I loved the expressions in here.
My favorite has to be where Matt is "screaming like a Lady." The animation on the TV is a nice touch. Are those old animations or stuff done just for the short? Either way, I thought having stuff on the TV was a good thing, as opposed to having a flashing screen or a still image on there.

The lighting too, it's not hyper-realistic mind you, but it doesn't have to be. It's simple and subtle and adds to the mood, as well as matches up nicely with your style.

All that said, I don't like to give critiques, personally, without being asked, and IMO you shouldn't pay attention to the stars over here -->

You did a fine job, the piece is funny and did what it was supposed to. I just hope these notes help you with making the best of your gags in future works.

Ha ha, it's always a treat for me to see some of your stuff pop up in my inbox.

Nothing much to critique; because I suck at flash LOL But It's hard to come up with ideas (I've had that problem).

So all there really is to crit, is that it's to short xD But it's better than nothing, so I ain't complaining.

The best thing of it is Tom having the same expression for the whole thing; 'cause I can see him doing that. And Matt is just Matt for the whole thing. And Edd, is, always the same. It never gets old!

Overall, awesome. Hope to see more from you in the near future ^^
