Thanks :) The drums were composed in a program (Addictive Drums). As for the bass I know, for me there's too much and not enough bass in the same time, because when I listen to it on speakers and AKG K-99 headphones it seems to be ok, but still it's not so selective as I'd like it to be, and when I listen to it on my mp3 player using earphones, it seems like there's too much bass, but obviously it doesn't make it any more selective :) I'm not professional sound engineer, so... :)
