From the name and start of the song, I thought it would be a bit of a stealthy "silent assassin" song. The sudden speedup at 0:07 caught me off-guard, as if you'd been spotted. I like the pigeon sounds throughout, although the use of literal pigeon-sounds can be a bit of a cheap way to make a song fit the theme (which is why I like the use of a bassoon: flutes work really well for these types of songs). The ending also came a bit unexpectedly; I would have either finished it with a nice ending or made it fade out.
I am curious as to what your mindset was when making this song. Overall, I do really like the song, it sounds great! Well done :D
