I like how flexable the colour-changing aspect is. It gives a slight personalization to each person who'd waer it.
I know it's for rave-parties (so the flashing, attention-grabbing lights are nescessary), but I would like it even more if it could just stay one colur, without flashing/changing (but I've never made these kind of things, so I'm not sure if that'd be too much for one mask). Oh, and maybe I was seeing it wrong, but having the little tubes be a different colour from the mouth-piece was a great idea!
Keep up the great work!
