Hi Dave, this is Karl from Newcastle (Australia). Cool tune man. I grew up on Satch, Vai, Yngwie et al and can certainly appreciate where you are coming from with "Hellucination". Smooth virtuosic stuff there definitely. My only suggestion is for you to add spice by incorporating some different effects or tones (eg, as in Vai's "Blue Powder") but that's a very small suggestion and one I'm sure you are aware of. :o
