Hey there keicho
Just a thought... Even though I love Symphony X as you do... I'd think of a million bgm that would match better than that one for your animation...! Your drawing skills are very good, keep up the work, but you should try and sync with some creepy music and I'd die to see another of your animations like that! :p
I couldn't stop myself from laughing when the fly rolled over flying slowly in the air at the beggining when I should've been creeped out...
anyhow, love your work, but improve audio plz!!!
