Critiques.. Please? :)

I was making all different kinds of cards.. I was thinking about opening a shop on Etsy to sell them in. I can make cuter cards than this, this is just what I had gotten done today. I plan on making many more in alot of different styles. I would like to hear your opinion about my work. Thank you so much. ((The military && the happy bday cards are my favorite)) P.S. I would also like to know if I had opened a shop on Etsy if you think you or anyone else would be interested in buying? Once again.. Thanks for all of your opinions. --Cassandra
