That first one with...looks like TO...is WAY too big, I don't think there is really anything that can be done to reduce it's size to fit here. The limits are 80x80 and no more that 6KB, that's pretty small so having anything animated is really tough and that's why you don't really see animated AVs here too much.
That first one is 125x125 and 156KB.
The second one may be able to be reduced somehow to make it work, it's only 100x100 and 7.58KB. Problem is I don't really know how to work with animations. I've had this same Burning Man one I'm wearing forever, joel made it for me but he hasn't been around in a while.
You might just wanna go with something that isn't animated.
