lol u think those soundcloud waveforms are accurate?
Yes...
Anyways these mixes basically sound like demo mixes...Actually a lot of demo mixes sound better than these. It's good for a demo mix in that it basically gets the rough idea of the song across, I can hear clearly all of the instruments and what they are doing, but it doesn't do more than that. I wouldn't be charging money yet, but if you do, and people think its reasonable and choose to pay, I don't see a problem with that. I would probably advertise it as demo recordings though.
As far as real mix critiques...
1. your drums need to come up a lot. The drums are the biggest downfall of this mix. They definitely need more than just coming up in volume too, they need to be remixed also.
2. You also need more low mids in the guitar tone, did I understand correctly that you used a JVM with a guitar rig cab sim? Either way, you're going to want to experiment with other cab sims or other mic positions and cabs, the guitars sound really boxy and small.
3. You might want to try splitting the bass track into a distorted and clean track, there is too much separation between the guitars and bass IMO, and getting a grindy and middy bass tone going could help that. Also fixing the low mid in the guitars would help in that aspect too.
4. Vocals are too loud.
5. Your master bus is also really smashed, there is a lot of audible pumping going on and the mix has no room to breathe. Somebody earlier was right by saying you can actually see it in the wave form. If you listen you can hear the vocals ducking the rest of the entire mix with pumping.
I think maybe your big problem with this mix is that the guitars are so thin that separation was just easy to achieve...but that's far from enough. You can clearly hear all of the elements, but the balances are still far off and none of the elements actually sound very good.
