Description of feature
Maybe as a feature make the tentacles more long and droopy like in the original,
I always thought the current tentacles were more lifted up and shorter than how the original design of the witherstorm had looked.

Other
The tentacles could maybe also be more blocky, like in the original game the tentacles looked more like much more several blocks than singular blocks.

Also another feature could be it destroying the nether portal, maybe an animation or something like that.

Note: if this is insane coding I don't mind this idea being scrapped.

ORIGINAL IMAGE OF WITHER STORM

I like this idea.

This has already been suggested and denied: #47

Tentacles breaking portals has also already been suggested and denied: #49

this is a duplicate, the tentacles are already accurate to mcsm. you can close this

this isnt a duplicate, its about tentacles being a bit closer to the ground, not about moving

Cracker has stated he will not be blockifying the tentacles, although I do like the idea of them being more droopy

Is this what you mean?

it looks like a tail in phase four, maybe turn the tail into long tentacles too.

I think this is better:
