I gave this girl a bday card?

Her i think she has the most beautiful smile and eyes... she had no idea i looked at her like that prior... do you think it was a give away that i like her? .. ever since she read it she's been a lot different towards me in a good way though
Update: oops. i meant to start that off with " telling her i think she has...." **

I want to send her a creative card, so I saw some article about design of the greeting card on www.amoyshare.com website, I try to use the amoyshare photo collage maker software to make baby cards, but the feeling is not designed very satisfied, Is there anyone who can give me some suggestions, Whether should I send a card?
