Hits the spot
What a strange and unique song, i must say. The style and tone is both haunting and charming at the same time. In my mind i saw a cross between a carnival with a sense of magic and mystery about it and the streets of Paris on a dreary, rainy day. Again, great imagery in your song.
This was a shorter song than i would have expected, but it worked well in that length of time. If it was longer i might have gotten tired of the repeating chord progression; any shorter and i would feel that it was incomplete. If you were to make this any longer, i would suggest to play around with an alternate chord progression to act as the bridge of the song. But i like it the way it is at this length. (have you considered ending with a different chord?)
If there is any criticism i have, its that now you have created this great song, you need to find someone who actually plays the accordion and record them instead of using the horrendously fake synthesized accordion. Your song is written, now it needs a soul.
I know what you mean when you say that you have put everything about you into your song. The music you make will most always have meaning behind it-a story or image or emotion, but in any case, your music should always reflect a part of you. I would say the main reason i like your songs so much is that they seem so sincere and deep. I would be severely disappointed if you started producing music that was as artificial and soulless as most things i hear on NG most days.
Again, fantastic job. Never stop creating.
