Those are great cosplays, I actually cosplay myself but have never had the urge to do Foster's simply because of 2 reasons:
1. This is the kind of cosplay you'd need more then 1 person with to do it right.
2. Possibly might not get recognized
no offense.
But I support those who did cosplay and I think you guys did a great job, I think the Frankie wig (if that is a wig) looks a bit strange but nice none the less. Especially the Bloo costume.
Also this is a tad off topic but for those of you who care, this is my cosplay page and if you like, you can see what I've done over the years:

It's mostly of anime but I have some other odd outfits in there, plus galleries of other cons I have gone to. Enjoy!
