Build looks nice. Rare to see people build castles that use and follow the terrain.
As for some constructive criticism: the torches everywhere and those big ass flags are rather distracting.
If the lighting is a matter of mobspawns, then you should use something like Magnum Torches. You can get much better atmospheres that way. If you want light in all those positions, then you can hide a regular torch in a hole by using microblocks, and the light will still shine through.
And some more realistic sized flags would fit the build better. It is like 12x22 blocks? Bigger than the tower it is on..
