It's green. That's about it. There's no interesting and clever matching of textures, colours or patterns. Even if there were, the very fact that there is so much green just overpowers everything else, making this look like a shallow gimmick.
But yeah, stick around and look at how to introduce some thought beyond "let's wear the same colour" into it (not meant to sound harsh, but I can't really think of any other way to word it). At least your stuff seem to fit alright.
