many metal parts coz it's an ork, and a goff, so the colour scheme must be dark and "poor", but i agree on the "unfinished look", il try to take another pic without the same light to avoid the "truck" style ;-)
The rust effect is nicely done. There seems to be too many metal parts and those are not defined enough. Picking out some of the finer details might give it less of an unfinished look.
