RWBY Day is likely suppose to be RWBY-centric (as the name says).

I think Gundam is proposing a more general Monty-esque celebration.

I recall that his first animations are unreleased bcause they're pretty eh back then. The earliest known is Haloid. With Icarus being between that and Dead Fantasy.

He DID release last year what appears to be a very old animation on facebook, which has Sun's gunchucks animation in it. (There's some more but I don't really remember them)
