Name: T_Snail_showcase should be TR Snail_showcase (T_ marks general data, TR is specfic project. Might seem like a nitpick, but when you start checking against long lists of claims you'll get why it matters)
Clean: yes
Lighting: okay, ambient should be a bit brighter, otherwise good
Northmarker: present, good
Fits exterior: NA
Pathgrid: mostly good, just cut down the nodes on the bridge to one either end and one in the middle.
Illegal to Sleep Here: no, correct
Gridsnap: good

Bleeders:

Floaters:

Other: 
replace in_moldcave_exit00 with in_moldcave_nat_exit00 (thats what matches the majority of cave entrances and looks better)
add Misc_Uni_Pillow_02 to the hammock
remove the Potion_Local_Brew_01 directly below the lid of the crate as it would be hard for players to see, much less pick up, making it a wasted ref.

I'd like to see some more clutter on the furniture, just to make this a fairer showcase, otherwise pretty good.
