Here's what I think...
Hmm... this is almost 2 months old. Hope you get my review.
Anyway, here it goes:
- Try singing closer to the mic to get the natural bass from your vocals. Get a pop filter to keep your vocal recordings free of the mic booms.
- I don't have problems with the instruments used, but you need to EQ and pan these so that they do not disrupt the voices. It seemed that everything is centered... it makes the recording... swampy.
- I think you don't need to double-record your vocals (did I hear a triple?), but it seems to work at some parts. Try adding compression to your vocals for a more level feel.
Voted five, but 9 in the review. ^_^
