Any chance of a top view for the forest? I've built that style of forest for small scale games but it honestly never occured to me to do it for 28mm.
Here you go

Wonderful. I'm with Jens - nowhere near enough pictures! 
The only thing that looks a bit strange to my eye is the raw lump of polystyrene composing the motte... 
Did you consider texturing the exterior of the hill with filler and then grassing it? (Or maybe that's still in the plan - I know you said it's not finished)
But a very impressive and evocative piece whichever way you look at it.
yeah,

I have not done any work on the 'ground Work' yet, there is plenty of basing materials that I will add at the moment I am working on getting the walls and buildings to a point where I am happy, then I will move on to the earthworks.
Oh and I forgot to post updated pictures of the Pyramid.
Not exactly how I would have done it if it was for myself, however its what the customer wanted and they are very happy with it.

Cheers all.
