Arc welding !
In the beginning as you fade in. IMHO, experiment with a 'plateau' fade in, bring it in from -INF up to about -21db fairly quickly and pause there for just 2 or 3 beats ... then fade in the rest of the way. The listener is 'hooked' because they can indeed hear that the song has started for sure ... but you still create that 'tension' element with the fade ... in ... You could have several plateaus ... :-| ,

The lyric in the very beginning, from 0:13 to 0:16 is difficult to understand, and later around 0:30, I have a little trouble with the lyrics. On the second listening they are much more clear.
On the second listening, at 0:35, I want more of that guitar, rather than so MUCH bass ...
Well, I didn't really need these phones anyway ? Hot as hell at 0:47, the understandablitiy of the lyric here suffers a bit, it's getting covered up as the guitar and it's raging mids ... is very close to the same frequencies as the vocal. On the second listening the lyric becomes a bit more clear, so it's the mix, not the performance here.
I like, getting hit hard here ...
At 1:09, this single vocal is a little low in the mix, it's good, let it out on top of the mix. With a cleaner vocal and massive dirty stuff howling around it, I'm thinking about sending all the instruments to one bus, and compressing them all together, so you can watch a single meter for the instruments and then compare that to that fragile vocal at that point, so you can be sure and have that 'seem' to be on top ... you could try running this through the Soundforge smooth-enhance and enhance one degree.
Again at 1:30 you are flogging the vocal with these vicious mids in the guitar ... but that's cool somewhere in the tune maybe, but not all the time.
At 1:52, run that bit of the vocal track through an 'enhancer' and mix a dry sharpened track with a wet track. On second listening, things are of course much clearer lyrically. I like the pie-anner ... tasteful.
At 2:14, the guitar duplicating what the piano has been doing just before it is a nice technique, I could hear a string tremelo section here in this part, or just a wash, and yeah, the vocal is getting eaten up there ...
At 2:36, I could hear a string wash, heavy with high violins, soaring over this section somewhere, fading out at 2:58 as the vocal comes back in.
The mids in the guitar are shredding the vocal at 2:58, can barely understand the vocal, second listening it doesn't get much better with respect to understanding the vocal.
You know how I treasure the vocal for all of our efforts, and especially your creative use of backup vocals, they are golden ya know, even if they are more like depleted uranium here !!!
I KNOW, you have just written this and that's great, I mean wow, neat piece of music, and I know you have a long way to go here ? Can't wait to hear this with the typical Sluice shine upon it. Interesting piece of ... work !
Now please, I'm going to ask you to whore yourself and bump my violin track to the top for those that come on later this evening ... THANK YEW !!!
And thanks for sharing.
