Welcome.
First of all the guitars lack body, sound like they are kind of distant but not really, and need to come up a bit. The mix also lacks a lot of low end so the bass needs to be turned up.
Drums. The snare needs to come up and needs more constancy/body. This could be achieved by compression or sample replacement. Same goes with the kick although the kick is fine.
I think the vocals sound alright for the style of music, just everything needs to come up around it so that it sits nicely.
Hope it helps, but I'm sure there is a lot of people that could give far better advice than me.
