Thanks for the feedback! I don't know what to make of some of your comments (especially the PSX one and the one that mentions crescendos are more than just making things quieter??) but I think I get you on the rest.
I do tend towards focusing on the arrangement instead of humanizing, so I can understand the comments about mechanical attacks. I'm puzzled by your comments about the sample quality, though. This was done with GPO, which I understand isn't the highest dollar sample library out there, but I think it is more than adequate. I guess GPO just rubs some people the wrong way.
I'm also puzzled by your comment about it lacking intensity in the sound? Is this related to it being mixed somewhat quietly? Can you be more specific about what sound you were hoping for and not getting here?
Incidentally, I loved the comment about Marble Madness on LSD. That is a very good way to put what I was actually shooting for!
Thanks again.
