Aw, cheers for comments & feedback everyone - much appreciated and some very useful tips too... ;)

yeah, listening back to it after some sleep has made me notice the low end's in need of a lot of improvement, I'm going to have a tinker with it and see if I can give it a bit more definition. I do want to keep just that one lone main kickdrum really, I don't want the bottom end getting too fussy, but it could definitely do with more work bringing it out. The hats could do with tweaking too for sure, I always find them difficult...

That's what happens if you ignore good advice and just sit there chain smoking spliffs and staring at a computer screen, without having a break and listening to something else for a bit - it screws your ears up and when you listen back to it the next morning...
