Wow! I hope to find a cave like that someday! 
That must be where Harvey stores his extra-special Easter ears!. 
Now there’s a reference I never expected to hear in the third millenium 
I pull my hat to you. The one with the holes in it!
@sheralmyst I just checked this topic. My impression is that underwater caves now look great. The dry ones seem much plainer and less attractive. The original semi-organic cave surfaces lent a more alien feel than the dug out rock ones I seem to see all the time now.
The Narrow Caverns Experience.
Starts off, simple enough with a grassy entrance…
But soon you find yourself at a sheer drop-off into a cavern that slips beside the deep impenetrable bedrock…
You then find yourself slipping through gap after gap… either vertical…
Or mostly horizontal…
It’s a lot of fun when you find these. Usually on mountainous worlds with minimal cave entrances.
Just make sure you can dig your way out if you end up lost and can’t find the way back 
Those “cave warts” are a real gas! 
The current look to caves is nice, but, for me, not as alien as the weirder ones in the past. I also miss the organic look to caves’ ceilings.
They often look like burrows of giant worms & not so cave-like.
I do like the variety of some cave systems & the huge caverns that are sometimes deeper down are MASSIVE & fun to find.
