The gallery itself isn't that bad but it is missing a little punch...sort of boring...
Here are three samples that you might want to take a look at.
Please note that we took the graphics that Amp did for our tour and just manipulated them into our galleries....

I hope this helps you with an idea of what works for us...
There are many variables to consider when making galleries.
Good Luck
