I'm impressed that you were able to find a piece of art that specifically had to do with eggs and outer space. (I'm also surprised that johnfn is still doing EGG compos in 2021, but that's neither here nor there.)
I've always had this internal expectation that pieces with EGG would be goofy and cheesy, but I enjoy how this piece is amusing and manages to be in on the joke while having class. I certainly get a sense of outer space shenanigans and I like how the piece incorporates that three note pattern.
The structure of the piece is pretty good; I enjoy the structure and flow of events that keep the piece compelling. I could have used some more velocity on the notes, particularly the EGG pattern, since that's the one that is most prominent - just something to give the notes a bit more sense of phrasing and not have each note hit the same.
Overall, this piece is a haunted egg waltz and I don't think I could say that about any other entry, lmao. I like the outro the most, especially when those higher notes at 2:39 re-enter. That slowed down version of the part from the beginning was an interesting change of pace that allowed the entry to conclude in a satisfying manner.
