Another building from Sandpoint in progress. This time the garrison.

I'm posting this up now, as I'd like some opinions on a technique, but first a bit of background.

I see this building as being one that was first built as a wooden structure, with earthworks to defend it. As time has passed, and the town has grown, it has been fortified to it's current size, and structure.

It hasn't gotten all the way to crenellated battlements, yet.

So, I want to show the origional earthworks outside the walls...

Basically I just want a ring of raised earth, that now is covered in grass, that surrounds the walls, except the entrances etc.

I suspect this will be done somehow with a layer mask...But what would you do?
