Finished washing the second suit and added the granite tones.
Dismounted the suits to work on the bases, they are looking a bit too light so I'm thinking they need another light bit of wash on the gravel areas. But otherwise the bases are just about done, there is very nice grain/mist pattern on the surface and it looks quite a bit like actual shale very happy with how the bases came out.
I'll be working on the third suit some more tonight and then I'll be ready for adding highlights and final details.
