Rock Mix

The guitars and bass seem to have a nice mix (with reference to each other). The bass could be a tad mroe punchy and have some more sub to it, but it could work as it is too.
I would personally turn the drums and vocals up. Seeing as though it isn't metal, the drums could probably drive it abit more.

It's sounding good for a demo. If the time permits I would maybe even produce/ layer more nuances into it.

Good work.
 
Sounds good overall, nice and tight. The only suggestion I would make is to try and make the guitar and vocals not fight each other so much during the verse (it's fine on other parts). Maybe you could EQ the vocals, guitar, or both. You could also try adding reverb to the guitars to put them a little further back in the mix.
 
Real catchy with good harmonies. I'd like to hear some more in-yer-face grit from the bass guitar. When the vocals drop put in the middle the overall dynamic seems to drop a little as well. I know its not a guitar solo but it could be more exciting, or at least the guitar could be louder.
 
The vocals sound pretty nice :)
The bass guitar has some mids/low mids that I don't really like and I think it doesn't blend in with the mix very well. Kick and snare sound a bit too robotic for a rock song, imo.
