Perhaps the issue isn't the "brownish gold" color, and instead is the blue color.
When you think of a gopher, what do you think of? A furry mammal, sure, but what about his environment? Earth. Brown soil, green grass, clay, etc etc. You obviously don't think of anything blue (water, sky) unless you have no idea what a gopher really is.
You have a potential mascot here, put him in his own environment.
Also, please add more color variety. The blue is extremely overused. Bright colors like that should be used as accents. It's also the same blue color over and over.. the only thing that separates elements is a drop shadow. It makes it hard to pick out what is what. You want certain elements to stand out drastically (like the navigation) and you don't have that now.
Aside from that, for the overall design, I suggest that your graphic-designer-Fiance read up on typography design, and maybe doing a few modern photoshop tutorials. Here is a list of useful resources for an earthy/green design:
