Too err... how do I put it in a better way? Oh heck! Too vulgar. I genuinely think that you're trying too hard to fit the picture into your theme, by using an unnaturally desaturated foreground to represent a boring present/past, and a not so outstanding saturated background (maybe even not saturated... but blue is quite close to white, which doesn't make it any outstanding in already an almost "grayish" scene. Take the word "gray" with a pinch of salt here) to represent the future.
The pier isn't a good place to create the tunnel-effect of moving from past to future. Unless you can prove otherwise, I really think that the real problem with the picture is just using the inappropriate subject to fit the theme you wanted.
