Jeremy -

With respect, it still sounds really bad and out of balance. Here are my comments:

- bass and piano way too loud
- crash too loud
- drums panned left and way too low, can't hear the kick
- whatever tuning you did on the vocals sounds very out of tune and very odd, definately not complimentary, also vocal level is way too low
- lead guitar panned right doesn't do anything for me
- you only mixed 1 verse and 1 chorus why not the whole song?
- reverb isn't complimentary - piano has too much why not try a reverb and delay combination on differnent parts?

Frankly, it almost sounds like you were trying to do a bad mix on purpose - are you testing us or something? Listen to EWF's mix and compare it to yours.

As for mastering. Let's forget the formal mastering process for a minute. Let's say I'm your client and I just want a good sounding demo and I want you to do it soup to nuts. The contest is to do the best sounding mp3 you can.
