I created the birds in illustrator CS3. It is completely vectorized. If you have any request that want to be included to the pack, just write it in comment.
As I've said before, I don't usually leave English on my synthesized clipart because I like it to be international. In this case, I left the "Merry Christmas" and "Happy New Year" parts because they seem to be a good part of the design. I left the banner on the bottom and the left hand side empty. The one on the left could possibly (and was originally) used for the year written vertically. And the one on the bottom could have an organization or a name written in it.
