It's likely too large, but ask @Velocio

It's too large.

Gifs have to be tiny to be accepted as an avatar. By tiny, I mean less than 4KB.

This restriction is by design, avatars appear on so many pages and unlike a picture thread where people are choosing to see large images, avatars on every thread. Threads should work on shitty mobile networks in the back end of some remote place, and so avatars are restricted to a really small size. It's big enough to enable a photo quality avatar or a simple animated gif, but not big enough to allow large photos (which we'll forcibly resize) or large/lengthy gifs (which will just be rejected).
