And this is ook22's side project? Geez, puts my major projects to shame.
Love the angle of the castle (i.e. entrance is on the corner rather than on a face), the use of the window piece for the front gate, the bows + robot arm in brown as ballistae, 1x1 headlight bricks as windows, and the 1x1 corner panels as crenellations. I also kinda like the notches in the 2x2 macaroni bricks - I think it complements your micro castle's walls.
Some tan is showing around the corner towers. If that wasn't intentional, maybe you could use blue plates in that area instead (Although it appears you're using a tan 32x32 baseplate)? Also, did you run out of green 1x4 plates?
So will your next model be miniland scale?
