First point, possibly the  most important: this is a song.  It's really hard to appreciate what a given song aims for without the music behind it. Music could turn this into anything from a roaring, heartfelt lament to something someone could use as a light ditty on a yukele.

 The theme is of lost love.  The singer clearly idolises the woman and also regards himself as generally   to blame for the breakup, but still desirous of some kind  of relationship  -- "friendship",  even  -- with the angel who has run away from  him.

But, is it? The line "Wish I knew where you could be and bring you back to me" means the object of his affections has run away.  That implies some sort of frightful behaviour which  has terrified the woman away.  "[T]hough in  the end /  I made you cry..." adds  to this.

At  its heart, this is a song sung by a liar, and possibly quite a cruel one.  It's not  the question of  deceiving the woman as such which brings me to this conclusion,  but the fact that the singer character has so  little understanding  of himself.   He regards himself as pure and complete with the woman -- yet still he did something terrible to drive her away.  This  is really contradictory and quite interesting: he idolises  both himself (in his ideal state) and  the woman.  That  way madness lies -- but then  madness is quite cool.

The atmosphere for this would be set entirely by the music.  As I've discussed above, when you look fairly closely at the words, the scenario is a little more subtle than a basic lament.

 I don't  feel the imagery is so strong -- but again I may be missing something.  The main visual components comprise the angelic, undescribable-ideal woman and the singer's own legs: "Walkin' with a broken heart' is nice and physical, as is "down on bended knee".

This might be to build a contrast between the heavenly woman and the ground-based singer character.

 The  singer character's language is entirely metaphoric: we're left with no real trace of the woman as a character -- there's no sense of her physicality or character beyond the character's insistence that she is what he desires.

On the question of over-use/cliche... well, yes...  the ideas  are rather worn through, but I do like the overall additive value of having a main character that is  so unaware of himself.  The cliches really start spinning off into new realms when we get to "...on bended knee..." -- the customary marriage proposal -- and you're left wondering about the poor fellow's sanity, scrabbling  around in the dust for everything and nothing  at the same time.
