The riffs are okay, not my bag of potatoes. I like your riff-work with Bulb much better. I am NOT diggin the vocals, however, for me they seem a little bit theatric (theatric can work in some instances - but IMHO not here). However, despite these apparent lows (for me) the tone is utter killage!!!
What kind of amp are you using?
Also, i like your idea about the NOMNOM, pretty fookin awesome. It would be cool though if the band was called "Not of Man, Not of Machine" Then you could actually use NOMNOM whenever the fvck you want! :)
