"How to paint BoFA terrain pieces?" Topic

So, now that I've made a serious dent in the forces with the completion of my goblins, I'd like to take a swipe at the terrain while I finish up The Good Guys.

I've primed the pieces with Krylon flat gray, but that's all. I'd like to create the look of weathered granite for the rocky areas and cliff walls, with the level areas grassy (probably flocked). (Though, honestly, they should be blasted stone if one considers the Lonely Mountain to be the habitation of Smaug. But that's not as versatile a look for the terrain pieces.)

Any advice on how to achieve this effect? (Hopefully fairly simply?)

That hill is now sold separately as the Citadel Modular Gaming Hill. Here's the online store link with one paint job:

And here's one from their terrain showcase:

That second one looks like a standard approach, probably what I would do myself: undercoat black, overbrush dark gray, drybrush light gray, highlight white, then flock all level surfaces with static grass.

I used a brownish green carft paint as the base coat, on top of a white primer. I had it thinned enough that it flowed well, but also covered well. I slopped it over everything that should be "grass". I then used a medium gray and painted the rocky areas. I then used a raw siena to kind of outline the rocky areas. I washed the whole thing with a brownish ink/future/water mix. Then I used lighter greens to yellow to drybrush the grass and then lighter greys to white to drybrush the stone.

I'm sure those Goblins could use another layer of highlights.
