Sure about that?
Well.... that depends. People tend to think of castles as the nobility and the servants, but there were MANY different classes of servants. (And it largely depends on the society AND the time period as well, but...)
Ladies maids, and Ladies-in-waiting, Lords-in-waiting, Equerries, Gentlemen of the Bedchamber, etc .. these are all noblemen/women as well, usually younger sons and daughters of a lord/lady of similar rank to the one they serve. If it's *royalty* they are serving, they might be heirs to lands and castles of their own!
Then you have another class of servants, such as tutors, governesses, and "companions". These could be noble or gently bred men and women who have no inheritance, or who have fallen on hard times, or second sons and daughters of the very wealthy, or *very* highly educated orphans/working class individuals.
A governess's job was to teach and care for the children, a tutor to instruct them, and a companion was, literally, a companion. Someone to sit and talk with you, listen to your problems, be a chaperone if they were beyond repute, sometimes to serve in small tasks, etc.
All of these people usually had their own apartments (a suite of rooms in the main house) although, a tutor might live outside the house/castle... and a governess might only have a single room, or even sleep in the nursery.
Then you have your heads-of-whatever... head of the stables (or stablemaster) head cook, head-maid, head-whatever. They were like... the supervisors. They might have their own rooms, their own homes, or sleep in a separate "servants wing" (inside the house) or "servant's quarters" (outside the main house)
Then you have all kinds of maids and cooks and gardeners and pretty much servants everywhere. These servants might also have (smaller) rooms in the servant's quarters/wing, or live off-site, usually in shared rooms. They would often sleep (ACTUALLY sleep) together - two and three in a bed. Sometimes the higher classes did so as well.
Then you had the lowest class of servants - pot boys and chambermaids and all the really icky jobs. These people wouldn't take these jobs if they had other options!! Usually they were orphans, or cast-aways, with no one else to turn to. They might sleep on the floors in the area of their work - stables or kitchens... or some (like chambermaids) would sleep in tiny little "rooms" in the attic or basement... often, barely large enough to hold a bed, and with ceilings too low to stand straight.
People in the lowest classes would sleep on the floors for two reasons: 1) They had nowhere else to go, and 2) For warmth! A large castle might have hundreds of servants piled up on the floor near the fires/ovens
Now... That's a very broad generalization for the time period between medieval and renaissance, and it's different in every land, so...
But, generally, the further back in time you go, the worse the servant's accomodations were, and the later, the better.
Now, regarding your map... some of the lettering is very small and I can't read it. I can't tell if it's meant to be labels or notes to yourself.
A smithy utilizes fire. REALLY HOT fire. Typically, that area would either be a stone walled enclosure outside the main building, or you'd have a stone roof. Straw+Fire=bad.
I don't know why, might be a shadow thing, but the stairs from your (round) tower look like they are coming out of the top of the tower, rather than the base!
Where's your gate? It looks like (to me, at the moment) the only way for your people to exit the grounds is through the castle, or by boat. You'd need some way to get horses in an out, at the very least, and preferably a larger gate for bringing in wagons and such.
A canal or pit or whatever to get rid of stable waste seems a very modern concept. Typically, there would be a servant whose job it was to muck out the stables, and they would put all of that... waste.. into a cart, or wagon, and the gardeners would use it for crops, or at the very least vegetables, as fertilizers.
Some even *sold* manure for fertilizer!
What's the round black thing near the round tower? Most of the shadows are great, especially at this stage, but something is off about the shadow near the smithy... I can't tell what it is yet :/
What's a horta? D:
