Oh, frabjous day!
A few differences other than color: 1) I extended the tab beyond the border of the stamped "card." The business card design unifies the front and back by wrapping the tab around (which is BRILLIANT, by the way). Since I can't wrap in this situation*, I thought extending it a bit would make my version feel more unified, and the results are lovely. 2) Bling. Because, well, you already know. 3) The sentiment panel is popped to add some dimension that isn't necessarily appropriate on a business card.
Still, I love this design and want to experiment some more with it. It's so versatile!
*I really, really want to make a card that has a tab wrapped from the outside to the inside of the card...a scaled up version of the business card. Wouldn't that be awesome! Feel free to steal this idea and tell me about it. Life sure had gotten busy lately, and who knows when I'll have a chance to pull it off!
