Good job mixing everything together, everything blends. I’m wondering what the vocals would sound like with the delay and verb dialed back a bit.

On the party noise, it’s fits, but I would recommend changing up the tone, pushing the drive a little more, maybe using a different pickup selection on the guitar. It sounds like there’s 3 competing guitars there all using the same tone, which is why that part may feel a little boring. Emphasize the solo a little more and make the interlude build up.
