Keep drawing Shiori's hair like this; give it some volume as opposed to making it completely straight. The reason why we reacted adversely to seeing the vew Shiori in a bikini was because you had drawn her hair completely straight and had changed her facial structure and even her hair color, thereby destroying any resemblance to the character. This version actually looks like Shiori changed her hairstyle as opposed to looking like a completely different character. Seriously, keep her hair looking like this and we won't have any problems. (Oh, and keep Shiori a brunette. ^_^)
Thanks for the comment. I've done some thinking and practicing, and based on it, I think I can re-introduce Shiori with a design closer to her original look, while having some decent construction. That was the problem with my earlier work- poor construction.
