Clean: Yes
Lighting: Good start, you got the values a little turned around "sunlight" is directional so looks odd in interiors, you always want it to be the one thats really low and then control how your interior looks with "ambient".
Candle on the table is too bright and causing the green light bug, the other light sources could actually stand to use larger radius's. Also would add some more lamps around to light corners or see about hanging a few lanterns. Don't go over-correcting or you'll just end up with more green light but still.
Northmarker: Present, good
Fits exterior: Yes
Pathgrid: Mostly good, you have overlapping nodes at the bottom of the stairs and could use an extra node in the attice
Illegal to Sleep Here: Yes, correct
Gridsnap: Good

Bleeders:
Misc_Com_Wood_Bowl_01: bleeding into the bowl below it along the rim

Floaters:
T_Com_Var_Knife_03: Blade would fall over at this kinda angle (would reccomend swapping to a knife with a more traditonal blade which you can angle more naturally)

Other: 
The two in_hlaalu_door should be in_hlaalu_loaddoor_01
goya/cyrodiilic brandy, shouldn't have these in a poor home as their supposed to be high class
With the nails, I'd recommend scaling them up so their actually visible otherwise player might not notice and assume their floaters
T_Com_Var_CrateOpen_05: These metal crates might be marked "com" but they dont really work outside of PC and SHOTN (Container versions are actually makred Sky), just swap this over to an open version of the regular crate. Also since theres actual loot, double check in-game that a bosmer and altmer player can actually reach whats inside.
For the attic check out the TD webs, you can find them under the GLB (Global) heading. More versatile shapes you can have around. (Dont have to use them by the by, just worth knowing they are there to play with)

Very good first start, always happy too see a showcase make full use of the TD clutter and liking the little detailing, though you seem to have run into the issue I normally fall prey too of focusing in a few areas and the rest being a bit empty. I'd suggest adding some extra furniture around too fill out the emptier bottom floor, also try adding more items in clumps, just as an example noticed with the bottles you had standalone try having 3 or 4 together, helps fill space.
