Kick and bass are well placed in the mix, so full marks there. It is proper rockin' at around 3.30. I like that demonic laughter. Always good. Lots of nice little acid blips and whirls.
What I would say is try to vary things more. What is here is great but especially at the beggining of the track, ie the first sectionwith beats, I would have liked more development to hold my interest.
