I really like that Gunslinger Idea. That's reaeeaally good and strong image.
But... rhymes. Rhymes are tricky things because if you struggle to get them to work then the poem suffers heavily. But if you get it right, you can get something flowing wonderfully. Your poems suffer from forced and obvious rhyme.
There's also some irrelevant lines such as the first one on Blank Slate.
"I'd like to take a moment, if I may"
... you kinda already have my moment and you're using it up with stating the obvious. Not needed.
But yeah, this isnt bad and the ideas are there. Strong ideas, good ideas. keep working.
