It's really a very beautiful castle! And your work on defense architecture is excellent!
I'm a little less fond of the courtyard paving. Maybe a more regular drawing would give better results? It is a good idea not to draw all the paving stones, but those that appear could be arranged more evenly? Not necessarily like square paving stones, with straight alignments, but still in a more regular and less random way? I think that's what made me weird to the eye at first sight. It is also true that we get used to this disposition after a while and that the proposed solution is also quite satisfactory.
