The performance is tight, and the singer is good. But the mix seems muddy. I think the culprit is the bass and the drums. Both of the them seem to have lots of low-mid freqs (~100Hz), and not much solid bottom end. The bass in particular seems to be very limited in frequency, almost like it went through a bandpass filter. I'd turn down the bass, turn up the vocals and guitars, and play with the EQ on the bass drum, snare, and especially the bass. Try to give the bass a solid bottom "thump" while also giving it some twang at higher frequencies. Just my 2 cents...
