The concept sketches are unfortunatly all in the guide book, which has just a very small size.

Kazuya Nuri´s work is definatly more solid than the work from the other character designers from the game, at the same time i found it kind of lacking in terms of unique characters, he is not as outgoing as the other designers :/ This way Apollo Justice had a slightly more serious tone, i have no idea if this was intended.
