Hiya mbuster,
Let me just start out by saying I don't go in much for the doom & gloom type lyrics, just not my bag. That being said & since you're interested in improving lyrics here's my 2cents. I hope you will find it constructive.
The insect metaphor is a good one & your first verse is solid. Good set up for your protagonist. Nice subtle working in of the bug theme.
The chourus has some kida obvious rhymes but it gets the point accross (gun lyrics particularly overused). Also if you are the gun you are clearly NOT the love. Maybe "your's is the love..." I'm nit picking but you want your chourus to really ring true. You might consider writing the first 2 choruses in a "before the realization" mode & the last one "after the realization".
The second verse is the weakest link. I'm not getting the sense that this is the turning point the way I should be & I miss the insect connection you worked into the first verse so cleverly. You can make the second verse resonate a lot more if you work that insect theme back in. This might be the trickiest verse for you since it wants to be your protagonists turning point.
The last verse is solid too, the return of the insect theme is welcome & that combined with the family theme makes it a good resolution & the strongest verse.
Overall it's a good early effort. The theme of The Man trying to keep me down & I'm gonna rise up is so standard that if you're going to use it you have to really put an angle on it...insects maybe.
Keep on writing!! It's the best way to improve. This kind of critique is so subjective that it will only take you so far.
