Almost there! The second stage of my RoBG is complete. I must say, this thing takes a load of work. I never thought I'd have to put so much into it, but no matter, it will all be worth my efforts in the end.
In this stage I did a heavy over brushing of Codex Grey on all of the rocky parts and payed close attention to the flatter more rock like rocks... if that even makes sense. The tile in the bottom middle and the features like it to the right and left of it are what I'm referring to. Anyway... After over brushing the rocks I then went back with the Brown paint found in the Citadel Scenery Painting Pack and went around the edges of the rocks to cover up where the grey had gone just a bit too far.
