They take me between 7-10 lunch breaks to do one of the Vocaloid characters after the model is painted. (Around 1/2 hour a time, so 4-6 hours work in each character).
I have several done. Miku, Teto, Akita Neru, SeeU, Gumi, Haku, Lily, Luka, Rin, Len and Luo Tianyi are all on my tanks and troop transports. I have another to do yet with Meiko.
Just no ponies involved so can’t share my results here.
