Hi Lynn,
Nice job. I like the tan, and the blue, but not sure about them together. I might try the red color in your logo as the background, or white, and see how it looks. This is too much work but adding a dropshadow so the tan appears to be casting a shadow on a white background would add some tasteful punch perhaps.
Of course whatever you decide on, all us artists will insist it must be something else
so maybe blue is cool and back to work.
Whatever the color, you've created a nice community here, and that's what matters.
