Wonderfully done except for the fact that you "misspelled" some of the graffiti, as everyone knows in the 41st millennium the word "kill" is only spelled with one (1) "L".... 
I copied some of the markings from the Blood Angels Dreadnought in the RT rulebook, it ha Kill with 2 "L", which is why I did the same. I plan to do an assault marine with Kil Kil Kil on his powerfist...
Fantastic!
Have you done something to the top hatch? I've got a few RT dreads and none look as crisp as yours
I haven't done much to this guy other than removing some of the mold lines (not all I can see on the photos). I guess I was lucky with the casting. I have a few other Dreads which are awfully cast and needs more love before painting.
