It's been a while since I've done one of these, let alone 3. If you aren't familiar with this little mini series yet, I basically do an interior in 30 minutes or less (in this case, each room took around 30 mins.)
So, we have..:

Barracks/Servants Quarters:

I tried to make this one a lot updated in terms of metadata, and tried to leave it more cluttered and be able to house more servants than the previous one.

Bedroom:

Attempted to be an upper class bedroom, possibly like a prince or son of the royalty. My inspiration for this room was an elegant Spanish prince's bedroom.

Herbalist:

This one's my favorite. Plants growing all over the place, brewing stands and potions, even a little messenger owl.
