So this is my Current progress:
Tommorow I'm going to do the little props and define the ground a bit more. Besides this I'm going to add the opacity maps (little decorations on the spikes, the water fading away, the trees seperate leaves, some carves in the roof, the spike wall on top of the house). After this I'm going to add some small effects like the smoke and make the background trees. These are going to be planes to keep the polycount low.
