Sewflake, I would change the blue scalloped layer to another color, still use the "Happy Birthday" sentiment, but use the "Tie One On" and the tie inside the card. The card is elegant looking, but the "Tie One On" and the tie seem to take away from that. Using it on the inside would be an unexpected surprise.
