I suspect that would end up cluttering the page and right now it's a good level of readability/findability. You have little icons in places to liven things up. I wouldn't make it more graphics-intensive unless indeed someone professional was able to give you a (different) design that could accommodate more images without turning into garbage. People aren't coming to marvel at how your site looks, they're coming to see if you are who they want to walk their dogs.
I was told by someone that it should be more "graphic intensive" like I paid someone to do it. So I get conflicted over that.
