Name: Enmenluat (add the TR_ prefix to it so it’s easier to find in the CS). Also, rename the file to TR_SteveInteriorShowcase or something to make it easier.
Clean: No, very dirty. Use TESAME to clean the file. The only things that should remain are the blank TES3 entry, the interior cell, and the cell’s pathgrid, as well as any custom items you made yourself for the int. 
Lighting: Settings are strange. Not enough objects like floorlamps and the daedric censers. Replace the blue lights with red lights to be more thematic. Replace the Light_Com_Candle_14_77 with a dark elf one. Silver is for common/imperial ints. Refer to my newly created Daedric Ruin Interior Style guide for the lighting (and just read it in general, it has good tips!)
Northmarker: Close, but incorrect. Use the bot on the discord server to determine the northmarker placement. (if you don’t know how to use the bot, just ask and people on discord will help)
Fits exterior: Yes
Pathgrid: Check it over again, there are places where the nodes don’t connect and should, or some places where the path could be made more simple. Also, delete all the nodes that are in water. NPCs should not pathfind in water.
Illegal to Sleep Here: No, correct
Gridsnap: Good

Bleeders:

Spears and spearrack are bleeding heavily into the ground
crate_Smuggler_01: one of these is bleeding into the wall
ingred_bloat_01: bleeding through the plate
Chest_small_02_gold_50: the bleeding is visible because the bottom isn’t a straight line

Floaters:

furn_bone_01: one end is floating
misc_com_plate_02 (x2): one end is floating
misc_flask_02: should be bled more into the table, as the bottom of the mesh is a point
misc_com_redware_platter: one end is floating a bit
T_De_StonewarePlate_03: floating, just press F for this to go down
misc_com_wood_bowl_02: floating
potion_comberry_brandy_01: partially floating
T_Com_Var_BottleBroken_04: back end is floating
T_De_StonewarePlatter_01: one end is floating
T_De_HackloPipe_01: not rotated to rest naturally
T_Com_PotionBottle_02: floating. Also, shouldn’t really be here, it’s too fancy.
T_Com_BookendRich_01: partially floating. Also, the wrong bookend. Should be T_De_BookendPoor
T_Com_SkullKhajiit_01: back of the skull is floating

Other:

Sound_Cave_Wind00: remove these, they belong in caves, not daedric ruins.
Sound_Cave_Drip00: same here. The water itself makes noise, no need to add these
adamantium_spear: as this is such a rare weapon, use this as an offering instead of having it just lie around in a spearholder
crate_01_armor_glass: remove/replace this, it’s too much loot
Remove/replace the potatoes, they are not a morrowind food. Use ash yams or kwama eggs or something.
T_De_Drink_BourbonGoya_01: remove this, this is a high-class drink, and the ruin is supposed to be very crude and inhabited by cultists. Overall, it looks like a kind of tea party down there on the tables, should rough it up a bit, make it less pristine and like you can find it in somebody’s living room.
T_Nor_Var_WerewolfboneDagger_01: remove this, it’s a SHOTN item
The daedric chant sound should be closer to the statue. It’s supposed to come from the statue, so that’s where the object needs to be.
T_Dae_Lord_Boots_01: Remove these. Way too valuable.
T_Bk_TelvanniConstructionTR: not sure why this is here
misc_lw_flask: too fancy for clutter, remove
Too many of your corpses have good loot. Make some of them generic (just bonemeal)
The rocks are positioned very unnaturally. Rotate them around a bit.
Flora_kelp_03: remove these. They are not designed for interiors.
misc_de_pot_redware_01: remove this from the pile of rubble. Idk what its purpose is supposed to be.
T_Nor_Silver_Seax_01: remove this, it’s a SHOTN item
Remove all the cattle bones. They make no sense.
Add in a couple more water lights.
Move the offerings to underneath/before the shrine, instead of on their own pedestal.
The clutter around the place makes it look like a house. Be sparser and dirtier with some of the loot. Those books set up like a library are too many. Also, too many skillbooks.
Add some more rubble (the vanilla pieces), especially to the underwater areas.

There are some good things about this int, such as your willingness to put good loot in it (although, it goes a bit too far). But there are issues that you need to address before promotion. Please read my Daedric Ruin guide and adjust as necessary.
