I've been procrastinating the Doomsday Ark since starting this Tale of the Mega Painters project back in January 2013. It's a huge kit with difficult to reach complicated areas. I had to paint it in 21 sub-assemblies, but after two and a half weeks it's complete! Lots of angles after the jump.
Here is a comparison shot with two recently painted Necron units. I only have 6 Tombblades and 8 Warriors left to paint for the challenge.
It's not the hardest model I've had to paint for the Necrons. That award goes to the Tesseract Vault which was 5 and a half weeks of painting edge highlights. Which is the hardest model you've had to paint in 2013? Tell me in the comments and post links to pictures.
