Thanks to all for the precise and encouraging comments.

@ Jilien: yes, the kick is a bit too loud, I agree. I just wanted the song to have nice, strong low base, but I guess I overdone it.

@ Raphael: yep, one speaker is louder, due to my decision to increase the volume of the guitar (panned almost hard-right) in the last moment. It's a learning curve - to be productive within a time-frame, but nevertheless  to pay attention to the detail.

@DP: Yes, I have a pop-filter and was using it, and this is why I got so surprised when I heard the pops when it was too late to re-record the voice. As for the other thing - it was the heat of the moment, really. My mistake.

@ Robert: on Ebay sometimes you see amazing instruments at amazingly low prices; keep an eye there...

@Ken: drums were done on Muse's own Drum Editor; I like more and more every day

Thanks again to all again for the feedback.
