Hi Robin- welcome!
Love the site! I love the idea- it makes me crazy when I have to go shopping at the same old chain store, stare in the baby aisle and wonder what the heck to buy for a baby shower. Plus, make sure I have to get a gift receipt because, chances are, someone else has bought the same thing!
As far as the sire goes, I think you chose a great color scheme and the font, etc is just right. I think it looks simple, making it look classy. When sites get too busy, it distracts me and sends me in too many different directions- so, good job! And good luck!
