Nice melody arrangement!
I love how you resolved the end of both iterations of the first section (around the 16th and 32nd bar, I believe). The second section (around 0:50) has a lovely melody as well!
I also like how you saved the intervals (excuse my lack of knowledge if I mistook the term) for the last part, emphasizing its importance.
Overall, I appreciate the effort of making pigeon music with few references to pigeons -- or at least, in a not-so-obvious manner. I'm looking at you, Peckathons' Symphony -- but still manages to reflect the nature of pigeons very well. Great job!
