Do you mean like in a group? Or with like a competition team? I've done group cosplay before lots of times - most of it was from my early days so there aren't a whole lot of photos. I've done one competiton with a group and it was completely terrifying.
No, I haven't posted a picture of me as Appa, since I just have con pictures of it. Not a nice photoshoot, of it.
Here's a con photo of it at least. I'll try to find a better one when I have more time after work.
Just a quick picture from the photoshoot! (It happened today instead of over the weekedn like planned. I expect the pic's will be edited/done this weekend.) figmentPez, this one is for you!! I know you like smiley cosplay pictures.
It's also more of a...blooper picture. I'm horrible at being serious, so this is me being me.
