Thank you! I need to get around to making myself a diy lightbox so I can get better lighting.
The girl is Hatsune Miku, she's a vocaloid which basically means she's a voice synthesizer application who appears as a hologram on stage in concerts. She's like a Japanese pop star that doesn't exist. I think she's awesome!
And the fellow with the cape is the main character from the anime Code Geass.
