The acoustics seem to have a little too much air/presence. How are you recording them? They're played well, but the way they were captured is a little harsh. You could try some notching and maybe a LPF to fix it. I think the drums don't fit the theme well. If you want that arena rock sound, the samples you're using don't quite work out, especially the snare and crashes. I personally think you'd be better with a jazzier/dryer kit and maybe using side stick on the snare as opposed to head/rimshots. This one is a personal gripe, and I know it's petty, but the fret noises kill my ears. You can probably use automation to reduce them, but they're always distracting to me. Keep it up, man!
