Design a simple 12 layers Animated greeting card

I am in need of some original "greeting card" designs that include some sort of simple animation as those seen in animated GIF's. Designs are for one side only (postcard style) and need to be 300 dpi, 4" height x 6" width, and animation divided in 12-15 PSD layers. Preview design submitted as animated GIF. The number of initial number of individual sample designs requested will be 5: Happy Birthday, Thinking of You, Get Well, Congratulations and Mother's Day. This is the beginning of a new project. If successful, many more designs will be needed in near future.
