Hehe. I grew tired of debating the authenticity of drawings after that last Italian dude, whatever his name was, had that site with H!P "paintings". I don't even remember what the hell they were in the end, photoshops, filter jobs, actual hard work, blood, sweat and tears, or whatever, but there was a ton of controversy, haha. I think mm-bbs had the most hilarious thread about it.
That's really why I initially didn't say anything. It was just the fact that people said it doesn't look like Aichan that was too funny to me. xD
Maybe the artist wants to answer these burning accusations himself?
