I love criticising so here we go!!
Bad Parts: I'm not sure where you got the guitar sounding instrument from but I'm sure it could sound better. With slightly less echo. Seriously sometimes, it can get annoying, when you try to hear the piano, and the other instruments. I get the feeling like it's getting in the way. At 4:27 that didn't seem like a pleasureable ending. There is either make the ending sounded as if you're trying to hard, but it wasn't that bad. Maybe your mind was clouded from working too hard in the beginning to the middle, but that ending was unnecessary, to me.
Good Parts: Don't get cocky, this is a great song overall. Just imagine me as the critic from American Idol. You had your good parts come mostly in the middle. And this gave me a feeling to chill. You're very creative throughout your song. You made me feel like I'm walking alone and then at 2:44, feel as if I was in deep thoughts during my journey. Then at 3:58, I'm walking alone with a purpose that I seem to have found. And I'm pretty sure you know the rest. Anyways, the ending didn't feel all too good but whatever, you did a good job. This music is for people who want to in a mellow state of mind.
Advice: Anyways, I don't know if you have heard of Nintechno "Memories", that's leaning towards my taste. Yet it's jumpy yet chill. Of course my taste probably isn't what everyone would want to hear so do what you do best and you'll succeed in you're own way. Also, I hope you change the way you stir my emotions at 2:44, I think next time do that a little earlier, and more often. It really makes the music interesting when you change instruments, add in more, fade out, fade in, crecendo, and alter the pitch, and other unique ways to change the song, I'm sure you'll be able to apply those techinques in other songs, good job though. it's very hard to get a 10/10 by me in music, movie, anime, book, and even food. I don't know if I rated a 10 on ANY music. Not even the best hit from Beatles, because the best songs I hear are remixes. Make a song better by adding or taking out. Music can be interpreted as a sword to me. Their is no such thing as the best sword in the world. It can always be improved, blessed, inscription, sharper, harder material by adding or mixing in. Like Excalibur, Masemune, and other historical swords. That was a work of art. I don't even think they are one of the best sword in the world but I'm sure there are better. I believe that the skies the limit. Just keep knocking on the doors you come across, and one of the infinite doors will lead you to somewhere. Well, I'm talking out of my ass again, well, it's best I leave the message here cause I'm too lazy to delete it and it's a waste. Anyways, goodluck.
