Thanks Bob! I actually did a lot of work on the cymbals, OH's and Room. The hi hat and ride cymbal bells were pretty shrill and piercing, and the open hi hat was quite loud, though essential to the mix IMO. If I hadn't worked on them, it would have been a lot more noticeable and brash.
I'm surprised you think the mix is very bright, as my trend the last few years has been generally 'darker' mixes. However, this one is probably as bright as I'd ever go ...
I used the 'tuned' version of the vocal track, and while the singer was not fantastic IMO, he did the song well and the tuned vocals were okay for me.
Something I was going for was almost a "rude" mix, if you will. In your face. I wasn't worried about fitting a certain standard or genre per se, I just tried to find the energy and intent in the performance and bring my attitude to it. Yes, I pushed the vocals louder than I thought would be anticipated. Yes, I pushed the backing vocals louder than most would. Yes, I pushed the guitars pretty loud. Yes, I pushed the lead guitar pretty loud. And overall I think it worked pretty good.
That said, when I go back into the mix and look at applying these suggestions, I will examine your points in detail and see what I can learn from it.
