Ryvius, you keep nailing it! I think you managed to obtain this particular colour in your voice that a lot of Japanese singers have. Out of curiosity, I wonder if you're singing with a complete understanding of the lyrics, or are you just familiar with the phonetics? I remember some of my friends singing along nostalgically to some old Japanese rock songs at a party, and when I asked in astonishment if they spoke Japanese, they laughed and explained that they had simply memorized the sounds due to long years of listening.
Also, I happened to look at Shademp's comment before I opened the attachment, and I somehow expected to see you with an actual carnival or alien mask covering all your face. Then I was caught by surprise

What are you going to do with the mask?
