I have both Lily Munster and Galaxy Explosion but I have never crossed them together.
Lily Munster has very short scapes that bloom in the foliage like your seedling.
You said that your seedling does not have rust, that is probably true because Galaxy Explosion will not get rust according to the hybridizer.
Your seedling is very interesting, looks like it has some stippling.
Your red eyed one is very nice too.
