Come on man, cut him some slack.
The original builder of the hull hasn't been around for a long while, and Genar's done some impressive work on the ship (I should know, I've helped him build it, and seen it live at our base). Even that proves he can do better than just build noob bricks.
As far as I know, complete 100% originality of the work is not an issue here, since the point is to prove you can do something with the materials you're given (including imported hulls, templates and other stuff). I also know that others on CBS have used Genar's work on the ISD as a base for their projects, so if they can do it, why not give him a chance as well.
