This is in no way bad. Its jsut it feels somewhat empty and naked with just the one guitar playing single notes the entire time. But throw some bass and drums on there and it could definitely pick it up a bit.
I think if you are going to make it just guitar you almost need to create an atmosphere with your playing and make your composition alittle more dynamic to fill in the void were the other instruments would usually fill in.

Right now it feels very boring.
Thanks for comments. You're both right. I will work on the background to build up an atmosphere(it's just my first recording and I can't use fancy music programs yet, gimme time ). I have also wanted some opinions about main melody. Did you like it?
