Yeah the drums sound really small and thin. It's hard to tell, but are you getting a lot of bleed in the snare track? It sounds like the hats are coming from the middle and the ride sounds kind of phasey. That usually means too much cymbal in the snare mic, but I don't know what you got going on here. If you're compressing the overheads, maybe turn it off. Really, when the drums are by themselves they don't sound too bad, so just drop everything else down some and let the drums pound through. That's the first thing I'd do to fix this. The snare also seems really compressed. If you're compressing it hard, back off a little or tweak it to let the body come out. Same with the kick. Toms sound pretty good. Guitars and synths seem fine. Bass is okay, could maybe use more definition. The vocals are kind of a trainwreck with all the effects and double-tracking, but whatever. It's Japanese. The performances could be tighter too. Not too bad overall though. Just some minor fixes and this thing will be jap-a-rockin.
