Given DD's love of girls in tight fitting leotards and bodysuits I've been wanting to see him do some art for Choujigen Game Neptune. One look at pics like post #1069243 and I'm sure he'd be inspired.
taking out originals, os-tan and busou shinki he's still got some stuff so he does indeed branch out. to be honest i was expecting to see some neptune and infinate stratos stuff from him, along with other mecha musume series. I was also expecting him to draw some symphogear when it came out.
