Card?
I think one here is more of a morse code than a card but this piece here is very interesting. I mean, it isn't like your others and say is a saying. I am trying to work on what it says actually, because it is bothering me, so you have my interested in that aspect. I think the lines you used for the text is good, but too basic. You have much white space surrounding them and you could have cropped this a but so the lines are bigger and easier to read. Apparently this translates out to "HELLO". is that correct?
~~THINGS TO IMPROVE ON~~
Less white space and make the text bigger to read the code more
