Don't make the same mistake I almost made, and thats creating fluff. There is a huge difference between using something to make your work look stronger, and creating something which has no purpose to it.
I don't mean to insult your layout designs, but it has no point. What relation does this have with what you're showing off? If anything it's distracting me away from your portfolio piece, which if a client views your work, they are going to pass your work off, and look for someone else.
And do you know why? Because they are going to think, "this guy spends too much time on something outside of his work, and not the work itself." I know because I had a teacher who is VERY much respected tell me the same thing, and he was right. I wanted to go ALL out on my portfolio with every little thing being HUGE. He told me what I told you and I finally woke up and realized if I am going to get hired, it better be because of my style, work, and skill.
So I am not saying to use a white background and slap your images on it, but don't make it pull away from your work. Keep trying.
