interesting middle picture. it seems very accurate. note the round tower upper left with the gun protruding from the firing slit.

also note the opening to the left and down which appears to be the opening for a garderobe (latrine) with it's accurately portrayed stains
the main figure's yat does appear to be longer than normal. as does the one in the dancing painting's leaping dancer.
the upper picture with the lad being shown how to parry, to me at least, looks like the blade contact is with the flat rather than the edge or spine.
all in all, a great set of paintings, glad you posted them, Sergiu!
