Some Saturation and Transient work will help a lot,,, this needs punch, not volume,,, keep the low's centered
Compression could still be done on some parts, maybe a bit on everything,,, but watch how the compressor is reacting with the low end
Try putting a reverb (highpass/lowpass) on the opposite sides of the instrument,,,
Keep the Bass centered, and if you want it to one side, bus it there and automate,,,
Maybe tune the drums (if your DAW can do that),,, or sample them, or added samples to them,,, Transient compression, or compression and transient shaping will help,,, Not sure how good the OH tracks came out, and if they are left and right tracks,, but maybe start the drum buss with those, trying to make them sound the best they can, and the other drum tracks bring them in a bit,,, Might be a lot of EQ low and high pass needed, maybe even some EQ notching..
Careful on the Parallel bussing,, sometimes it can cause the opposite effect of what your going for,,, might be a simple high pass on the parallel bus that would help,,,
I don't think I'd tune her vocal much, to me it's not that kind of song... But some thickening would be a good idea... and parallel some saturation in, and some places could use a bit more than others, and see what delay works better, might be good to sync with the tempo...
hmm is this tempo mapped ? that could help too,,, just a place or two I heard something in the drums,,,
Automation is the best thing a vocal can have, and to the snare, say in the chorus,,,
Use the same verb thing on her vocal, as I mentioned about guitars, but, instead of opposite side of instrument, bus it wide, not to one side since it is centered
Now all that said, I haven't heard the tracks individually(would love to mix this !!!) and I'm not a mix god, lol,,, Don't know what DAW or plugins you have,,,
I'm sure your wanting that heavy, punchy, full sounding radio ready mix,,, so don't worry about volume so much,,,
Good song, almost reminded me of Halestorm !!! Lzzy has some pipes,, lol,,, I'd try to push her by backing of her vocal, so she felt she had to push more, lol,,, might work, might not, lol, still good vocal though
Haven't heard this song before, is it a cover or original,,,
I hope your having a blast with this, I'm thinking you are !!! and doon't take a thing I said personal, your doing great !!!
