Really do love your matyroshka makeup. She is wearing brown full gloves in the picture(although I do know that Matyroshka cosplays besides Miku/Gumi are mostly designed by the person). Oh and watch out for badge photobomb in pictures.
For Camellia Teto, the first thing I noticed was the lack of a camellia flower(you're using a rose I think). It's actually pretty easy to just make one and attach a ribbon onto it so you have that correct too. Also the shirt should be more formfitted.
