Bro and Sis: Two Bunnies with a Mission

Some development sketches for a brother-sister duo. Introducing Sis, the extraverted tailor and Bro, the worrywart inventor. Totally different, but they can't live without each other. I thought of calling them Pins and Needles at one point, but it seemed too violent for such fuzzy critters. So Bro and Sis it is.
