really cool actually, i enjoyed the sort of melodic non-direction, although maybe a somewhat more calculated progression would be better. it's hard to tell and i like it as it is
old AT reverb isn't sounding too hot here. something more subtle with the nasty rvb freqs EQd out would sound a lot cleaner. but otherwise the sounds are very fitting
yeah as Opaq said, Flash reverb produces some pretty horrible freqs that need cutting, plus the reverb itself sounds very metallic, that metal sound is useful for some stuff but not this, just be mindful of how you use the old reverb and how you EQ it after :)
