I'm not a remixer myself, but I do have to say....this is one of my favorite mixes yet!
I love the Bowser theme from Super Mario 64. I was hoping someone would remix it.
I don't know what "EQing" means, but I too really think you should bring up the guitar. It added so much "mmph" to the whole remix. And it did get kind of lost sometimes with all the other sounds.
Besides that, great job! This is in the top ten of my remix list.
