Name: TR_Sliced_Bread_Interior_Showcase
Clean: yes
Lighting: Mostly good, ambient should be darker and more brown/orange than yellow though. Those darker tones match the color that ingame candles produce better, dont overdo it and make the room noticeably orange though, there a balance to this. Otherwise could use some more lamps/lanterns around.
Northmarker: present, good
Fits exterior: "no" not stated but seems designed for a ex_hlaalu_b_16 which is 2x4, not 2x3, though a little more space wouldnt be bad for this int
Pathgrid: Mostly good, two notes. First, dont put nodes in the middle of stairways: nodes are where NPC's stop and having that in the middle of stairways is always a pain. Second, the one on the cushion may "work", but will  just result in an npc trying to stand on top of itt, which needless to say would look odd, so just have the nod infront of it.
Gridsnap: good

Bleeders:
sc_paper plain: bleeding into the center of the table
food_kwama_egg_01: bleeding through paper

Floaters:
bk_specialfloraoftamriel: not touching the bookend
bk_redbookofriddles: not touching bookend
bk_AffairsOfWizards: not touching the above
bk_firmament: not touching the above
sc_paper plain: floating over table x2
sc_paper plain: floating over bookshelf x6
misc_de_goblet_09: floating over bookshelf
bk_BookDawnAndDusk: should be angled back a little more and touching the book end

Other:
due to how much its worth, never have more than one limeware piece in a poor int, the two bowls and a jug are the main offenders here, the platter could maybe be justified as a heirloom display piece
related to the above, flin is a high class import, better off swapped here for one of the local liquors, the Bug Musk should just be removed in that same vein
the tapestires with the tribunal symbols on them are as a rule discouraged in homes, better replaced with neutral ones
The skooma under the bed is too far under. "hidden" objects still need to be placed so a player can actually see and grab them, otherwise they are just bloating the interiors size pointlessly.
The bookcase next to the bed should be moved out, similar to the above in that it blocks players access to the content, but also in-universe its a weirdly cramped choice when they have other space. (And even more space given the need for a slight expansion to the shell anyway)
The copy of de-rerum dirennis should be removed for two reasons, first SHOTN's book covers stick out badly next to vanilla-TR ones (which is being worked on, but for now better not to use them outside shotn) and second, you already got "a game at diiner" shouldn't have multiple skill books in one claim.

An excellent first effort, fix the above and I will reccomend for promotion.

note about the skooma still applies the one behind the chest would be impossible to reach or see, the two chests as well rather than downscaled chest you'd be better off with either small chests or sacks.

Fix that last issue with the skooma (and the pathgrid if you feel inclined) and you'll be done.
