Glad to see the contiunation of your designs. On the subject of MU Riker, I would say go with the Borg implant too but I also think you should go with the eye patch but maybe have an cybernetic eye with it. I don't know if you ever read DC's TNG comic on an alternate universe devestrated by the Borg, but the alternate Riker had an eye patch on his left eye with an cybernetic eye I believe that was. I'm sure someone besides me knows about it.
Are you going to be doing more of the MU Titan
crew, such as those on the regular Titan
