It's not centered, the "accent images" look redundant and the salmon-colored text is not pleasant on top of the cheap "paper" background. If we're talking about grammar: too much exclamation marks means no exclamation marks at all. You use them sparingly, which in turn makes an exclamation mark much more effective.

Your designs seem to be okay, but they don't have any personality at all. If you are to sell yourself as a designer you need to start creating your own style instead of looking like much of the other designers' work on this forum — crap.

Example time: I am not a designer, I am a web developer. I work with designers and purchase their work (in which I code and use). So let's say you're trying to sell to me. What makes you think I'd like to buy a design that looks similar to other ones?

BTW: I am not saying you ripped off design or anything, I'm just trying to tell you that you need to stand out from the rest. This is all constructive criticism, I am here to help
