Simply fantastic! First of all, it must be said that this is a great team effort - from both you and the photographer. I really like how this is set up - from the high reaches of the castle where we can see the castle, the river and a good part of the rest of the city. One thing I really like about good cosplay is that it allows us to see characters in places where we normally don't see them, and that's certainly true here. I feel like I'm watching Cinderella make a state visit to Hungary!
Because I'm fortunate enough to talk with the characters more often than not in Orlando, the acid test that I have with Disney art and cosplay is, "Would I be happy to show this to the character(s) themselves portrayed?" In your case, I would certainly be happy to show Cinderella herself - and suggest that she visit Budapest already if she hasn't done so. Keep up the great work!
