Your guitar work is

, but your drums are a bit unconventional, it doesn't sound like a real drummer sat behind a real drum-kit, not in terms of how real the sound is, but drummers don't tend to drum that way.
Also your melodies are not so strong.
This is possibly on perpose if it is background music.
But if it is, to judge it well I'd need to know what imagery it goes with.
Your orchestral music (the Weavers tale) was a bit lacking.
Some harmonic mistakes where made, and it didn't seem quantized properly.
It does show that you understand concepts like "question and answer" and you can work with multiple melodic lines, but you need practice.
I can tell that it's not what you have specialized in as much as your guitar work.
But you seem to have general talent, the rest comes with doing it often.
My main advice is that even though you write background music, work on your melodies.
You work with lite motifs a lot (repeating short melodies) but your music could really use longer-lasting melodies to prevent your music from becoming too repeditive.
