Ryoko Demon as Captain Amelia from Treasure Planet is scary good and could not be any more authentic. Superb photography by Soldatov Vladimir aka Kifir and some great locations really bring the whole thing to another level. Ryoko has been featured on GeekTyrant before and the quality of her work means she'll be featured again in the future. Treasure Planet was not super successful and I'm sure the average person would have no idea who Captain Amelia is, but geeks like me, and hopefully you, do.
As a rare treat we have video of Ryoko rocking this cosplay during Animau no Haru 2014.
