First Rejection!!

Hi, I'm a relative newbie (since June) with just a few tracks up but I've just had a track rejected (an horror/occult/Satanic style cue) which is an alternate version of a track that I've previously had two versions of accepted by the same curator! Might this be because of overkill, or because the rejected version has alot of psychedelic effects towards the end? I see that the latest brief is for Art Rock and ironically this is probably the Artyist Rockyest thing I'd submitted thus far.
