Your mod list growing more and more powerful by the day? Wonderful, keep it up!
The shadow tweaks in these comments are great, have you already done all this?
I'm pretty sure you've already installed this, (Bug Fixes) but just in case it isn't up to date and you haven't thought about it.
This will probably burn some video cards, you said you were holding off on retextures till later for that reason, but maybe the future is now?
You'll have noticed renthal331 made those textures, while we're at it I recommend everything else they've uploaded!
Do your Khajiit ears show while helmets are on yet? I can imagine arguments for and against this, "clipping, buuh!" no, they've just cut holes in everything because their ears are important! Same reason their tails don't disappear for pants. Also this mod was made very considerately of all other mods and setups. Improved Closefaced Helmets, Horns Are Forever, and Argonian Decapitation Fix are necessary too and linked in the description, but you already have Improved Closefaced Helmets I think.
And maybe a couple new buildings? The Alchemist Shack and Abode, and The Ice House, both by the same author. If you read their descriptions I think you'll want them too, superb. Personally I would install everything else tzarbaby000 has made as well, but I'm not sure they'd prove as interesting to everyone else.
I think that's all I can offer, you have Simply Knock already right? I hope at least one or two of these are useful.
Thanks for reading.
