Now isn't this the work of Samulis that Waffles and NorskeD have been talked about?
You composed a masterpiece with intensive sections of movement. You piece has the unique characteristic and attitude of flow. In my opinions, the first and second movements are probably the most outstanding sections. However I also adore the ending (4th movement). It sums up the whole 'storyline' in a very excellent and creative musical narration. Finally, I think the brass arrangement is splendid! I am a 'brass lover' myself and I had crafted my skills in using it in the right place but your is absolutely impressive.
A truly magnificent work of music.
