Yeah man, you gotta get rid of some of that reverb. It's just kind of like a sea of mush right now. The vocal has no presence because of it.
The guitars are so scooped sounding that it's hard even times to make out the chords that are being played. They're just kind of all highs and nothing else.
You've just got a lot of things competing for the same frequencies, and it just sounds really muddy. I would try carving out some room for each instrument with eq. In other words, if you cut, say, 500hz in the bass, boost that in the guitars. I would say kill ALL the verb and start the mixing totally dry, trying to carve out some space for each instrument. When you do add the verb back in, I would say to not add nearly as much ... but that's just my opinion.
The drums don't sound bad in the beginning when they're by themselves, but once everything comes in, you can hear everything competing for the same frequencies.
The vocal sound is by far the weakest link to me---not the performance, just the tone. (Though there are a few sour notes that could be better. The first line of the second verse, for example.) It's total mud and lacking any definition at all. Some eq could help, but it will take some experimenting. Right now it just has an all-encompassing muddiness to it. There's no breathiness or clarity to it. The vocal sound is not flattering to her voice at all. It almost sounds like a karaoke vocal track. What type of mic was used? It sounds like a dynamic instead of a condenser.
Other than that, it's a nice tune. I like the use of the dominant IV chord in the chorus, or pre-chorus, whenever it is. The harmony guitar line is nice---kind of reminscent of "Melissa" by the The Allman Brothers I guess.
Anyway, take these comments for what they're worth--- just my opinion.
