Your Luna is a beautiful girl! She also looks so much like my Promise that it's a bit spooky. Promise has a bit more white on the chest, a couple more black paw pads, and no white on the cheek, but I doubt anyone other than you and me would know the difference. Since I don't have any kitten pictures of Promise, seeing these really bring back the memories.
Yes I'm so proud of her when I look at how much she's grown - when I got her the vet wasn't sure if she would make it, the guy I got her off was sooooooo dodgy and she was so young to be taken away from her mother, but she bounced back really quickly, nothing seems to bother her! Even now having eaten a plastic bag she doesn't seem to care at all!
