A drawing for the Warwick Castle idea. Self crit: The clouds are too dark, there would need to be more rubble so account for the damage created. Maybe have some damaged trees? I'm not sure on the hill and moat idea, that was just an addition for the landscape, perhaps the hill could be bigger? Rubble from the walls could be cascading down the hill into the moat, perhaps making a way across. I like the rough shape of the rocks and the way the castle is torn apart. Overall, I think this is a good starting point.
