It's hard to say "what's wrong" when you don't say what you are trying to achieve. I think there's a little pumping on the kick that sounds like a compression issue but maybe you want it like that. Overall, the mix suits the style of song.. dark and gritty. I quite like it. It's pretty dirty sounding in a good way. The only thing I am not hearing much of is the bass. I can't hear any bass lines at all.
What band is this? I think the song is quite interesting and i like the vocals. The mix has character and it's not overtly clean and sterile sounding like the fashion now.
