This had like the lowest score when I came here... Wut?
It's certainly not the best track out there, but it sounds fine to me. Especially considering it's the first thing of yours on Newgrounds.
The guitar sounded really good, so did much of the brass and the strings. The drums were okay too (better than anything I could make). The composition itself is cool too.
My biggest issue is with the slowdown at 1:25 =>
It simply doesn't sound natural, at least to me. I can't really give you any tips on this, but it sounded a bit odd. Also, I think the ending came quite quickly, but maybe that's just me.
Overall, good job!
