I finally think that this beast is ready for painting. Since this monster is now finished, I decided to enter it into Miniature Wargame Conversion Conversions' September Contest. I'd appreciate your vote here!
The last hold out was figuring out how to do the Inferno cannon on the sponson turrets -- IG Hellhound barrels are hard to come by. Ultimately, I punted and decided to graft the Flame Storm barrels on instead. Now, I just have to finish the other beast, and re-write the datasheet to fit with the new codex. Meanwhile, enjoy some more pics:
