Well, having just this moment done an A/B comparison (after not listening to it at all since I posted it here last night), yes, I think I am happy with it. The first of my mixes sounds a little strangled, this new one sounds much clearer, much more space. The hi-hats and the cymbals play their role much better as a result, and I could hear that semi-tone climb from the bass at 1:37 much better.
Is the bass too loud overall? Hmm, perhaps, perhaps not. Sometimes it feels a little too in-your-face, but then I kind of like its part in the song, so why not.
Also not sure if the guitar solo is also too loud.
I suppose the only thing I’d like to be more prominent is the backing vocals. Not sure which approach to take though: Better EQ, or by balancing them better in the L/R panning, or just turn them up! Or double them up?! Or…?
