Great progress!
Although it isn't the greatest thing in the world, it's over the average minute long "song" that you made originally, it's progressive with a background that actually changes, and those instruments sound beautiful together.
The ending portion with the scratchy instrument (maybe it's a guitar, maybe a saw, synth even, gita-san. I'm not totally knowledgable... shoot me.) portion was probably the only thing that set me off but looking at your older songs it's... completely welcome.
Perhaps without the ending it would be ambiance? Naw, you'd never do that.
