Dark abstract wallpaper

I made this a couple months ago, and I really like it for some reason.
Tell me what you think.

I don't really like this piece that much. There is a lot going on and no real point of focus. When you create something you want it to be visually stunning, and draw it's viewer to a certain point and built around that. For abstract, you want things not really to make sense and/or multiple points of attraction. What you have done here is somewhat random. For the points of attraction, which are thse "rust" spots there isn't that much going on.

Out of curiosity, how much time did you spend on this piece?

Guess I need more work. I probably spent about 20-30 minutes on this. Random is definitely a better way to phrase it. When I was making it, I wasn't thinking of making a focus point. I'll take your advice into consideration when I make another background. Thanks for the feedback.

Yeah, same as Tenchido. This looks like it could be a background to... something.

My desktop :P

Well yeah, I mean like a background to some sort of art. And that it's lacking the foreground/focus.

So as a wallpaper alone, it's fine, I guess. Just nothing amazing.
