Sounds good to me
Soft intro followed by heavy pounding was a nice idea for this heavy piece. Can kind of see kittens playing this metal music while another kitten gets ready to mew into the mic. Good demo so far.
The guitar sounds good and solid to me so nothing to worry about there when you get to the full piece. The keyboard sounds really nice so I liked that as well. The bass here is very smooth and sounds greatly easy on the ears. The drums being the last piece sound loud, sloppy, and awesome.
Overall, sounds good so far.
