''The shiny dance floor... The pretty party ponies... Ooh, the fancy band... Shiny! Pretty! Fancy! GOTTA DANCE!''
That's the first thing that came to mind while looking at this picture. You've really captured the character, not only in appearance but in her way of acting too. That's very impressive if you ask me, kudos to you for achieving that!
I really like your cosplay though, the dress is so fluffy and cute, yet it still holds resemblance to a real gala dress. I really like your wig too! It looks so pretty and curly, even if it looks very neat and tidy, it totally works Pinkie's mane! This probably is one of my most favourite Pinkie cosplays.
