Hey Pootsy, welcome! Always really nice to see someone posting a showcase. I've given your file a quick look over so here's the review.
Illegal to sleep: yes
com_sack_01_rnd_ingr_5 rests a bit awkwardly against the basket (tricky with sacks, they are not quite so rigid in real life, which limits how they can be placed sometimes, try to move it down a little)
com_basket_01_chpfood5 bleeds into floor
Com_Sack_02_Ingred bleeding a little too much into floor
com_sack_02_chpfood3 same, bleeds into barrel
misc_de_bowl_redware_01 not resting properly (See pics below)
same for all of the redware items on that de_p shelf
furn_de_p_chair_01, furn_de_p_table_05 sunk too far into the floor (multiple)
all of the objects on the corner table need rotating to rest properly (see pics below)
Com_Basket_01_POS handle bleeds into com_basket_01_pillows
com_basket_01_pillows basket of 25 pillows seems excessive for 1 house
active_de_p_bed_14 sunk too far into the ground
Com_Chest_11_clothing might be unsuitable here
light_de_lantern_03_128 not quite resting properly on the rope
furn_de_p_shelf_02 not attached properly to the wall
books on the bookshelf might need propping up with other misc objects
Alright, that might seem like a lot, but don't worry, you are on the right track. First and foremost the structure is great and the tapestries, doors, rugs etc placed with 0 issues, really good start, can't fault you there!
You'll need to pay a little more attention to how your furniture and clutter is placed.
Lots of the furniture in this int is sunk too far into the floor so the feet are chopped off prematurely. If you weren't aware, if you move an object over where you'd like it and hit 'F', the object will 'F'all to the ground. If the bounding box lines on the bottom of the object turn from solid to dashed, that generally means it's resting perfectly on the ground (though there are exceptions, it's a good general guide). At a guess it looks like you hit 'F' too many times or sunk the furniture into the ground a bit more -- it's not necessary, so long as it's flush with the floor it's perfect.
You'll also need to tweak the bits of clutter on the shelves and table so that they lie flush with the surface of the de_p furniture. Because the furniture is not horizontal with the ground, you'll have to rotate objects on all 3 axes to get them to lie well. See this comparison:
5 seconds of rotation work:
To rotate objects on other axes, hold down Z, X or Y whilst right click-and-drag. It might help to go File > Preferences... and decrease Object Rotation to 0.1 (makes it much easier to get fine adjustments). Objects like the redware bowls will need sinking into the furniture a little so they're not resting on extreme points that the model mesh has.
Finally a few more misc objects and bits of clutter wouldn't go amiss, with just over 100 references in the cell it's on the low end for a PT cell; try challenging yourself to add coins, bottles, cutlery, glassware, baskets, etc. to boost that up a little once you're feeling confident with how things get placed.
If you can go over the interior again and get all the clutter and furniture placed nicely, it'll be no problem to recommend you for promotion. Hopefully these tips have proved useful -- ask us on the Discord if you have any more q's!
