Gee, I'm going to sound so harsh compared to those guys above!  But...  This song rocks and it can be even better (IMO!).

What I hear is the old issue of wanting a certain effect on the vocals (or guitar, or...) and how that effect can sometimes make that vocal (or instrument) seem a bit lower and disconnected with the rest of the mix.  I would never profess myself accomplished in the mixing world, but I think the vocals need to be a bit more up front.  This could be done by more volume, removing other instruments taking up your space, reducing the amount of effect used or even (sometimes) something weird like adding the vocal track again without much effect but putting the volume low on that track.  It might add a little definition.

Another thing "I" hear is a bit of boominess and a lack of definition in the backing instruments (in other words, it seems a little muddy).  The boominess (if anyone else hears it) can be tamed, but the rest of the music could use some separation.

What I would suggest is playing it next to a reference track you're familiar with that's similar.  For example, take THIS (after the stupid ad) or, another from the same: THIS (at least the part in the beginning and the chorus).  Notice how much more the vocal stands out.  You have a voice that doesn't need to be hidden so I'd get it out there!  Here are a couple of more just to illustrate the point.  Check out the first track off of THIS Album Preview and THIS ONE (the part around 4:00 is similar to yours in the middle).

The bottom line, in my opinion, is that there's nothing wrong with YOU, you just need the music to be a bit better defined behind you.

Then, once you get this figured out, make a CD of these so I can buy it - I love songs like this!
