Music Need advice on a song I'm writing please

[Error 420]

It's at This Link and works on both mobile and computer.
Even if you're not musically trained, give it a listen and tell me what you think. Right now it doesn't have any sort of ending, and I'm very unsure as to how to end it. It's supposed to be kinda folksy and mysterious, but somewhat optimistic. If you have any opinions or advice, I would love to hear what you think.

 

[Yumiko]

I think this is freaking awesome!

 

[hmphq]

I would buy this song, bruh.
Amazing.

 

[KingofAesir]

Sounds awesome! Maybe end it with a build to a high note? I don't know, sounds awesome so far though!

 

[Twisted Talia]

Oh. My. Gosh.

I love this! You’re really freaking talented, keep up the great work!

I appreciate the compliments, guys, but I'm looking for criticisms more than praise.

 

[Saccharine Cyanide]

I'll bite the bullet and give criticism but only because you asked. XP

In some places, the harmony sounds a little off. I'm not sure if it's because of the chords or if it's something else.

I'm also not sure about the continuous sixteenth notes; they kind of distract from the the main melody where they should be supporting it. I think breaking them up with some eighth notes or rests could help.
