As far as additional mods, I'm also using Ambient Dungeons, Better Water, Full Grass, and Natural Environments.
Anyone else know some good visual mods that work well with OBGE?
Everything works with OBGE, it is just the matter of your taste.
I personally recommend to replace Better Water -> Liquid Water, Natural Environments -> All Natural, Ambient Dungeons -> Cava obscura.
All Natural can change the color tint of the world in its ini file if you prefer yellowish or brownish colors for example.
You might also want to add several other mods that require OBGE like Luminance HDR, Enhanced Seasons, Realistic Health, Screen Effects, Fearsome Magicka.
Some notes about shaders - those that you use are not the best out there (however it is subjective).
Try SMAA or MFXAA for antialiasing, HDAO for ambient occlusion. Godrays is a resource hog, if you already pushing your videocard to limits you can remove it and just replace sunglare textures (like Beaming sunglare or Realistic sunglare).
