Here's the progress I've been making on my land raider with the chapterhouse doors. I had to do some greenstuffing on the sponsons (the 'roof') where the resin was so thin it broke when I gently pressed the bits together. I don't have any GS tools which is a pain so I did my best to flatten the GS and then applied 3 layers of super glue which self levelled and made a semi smooth surface. Can hardly tell now! It assembles very poorly but with some pinning the look is good. I wouldn't recommend it if you're impatient and don't want to do some drilling/ greenstuff/ carving. Other than the crappy cast I like everything else about the look of this chapterhouse mod.
At this point, I don't think I'm going to add any more green to the model. I like it being mostly white with a green accent and this scheme matches my rhinos. Soon I'll be blasting xenos.
