Paph. Lady Isabel update

I think my Lady Isabel maybe is getting ready to bloom.

It significantly improved since I placed some sphagnum moss on the top of the bark in its pot and moved it into orchid tank. The color of the laves is still lime green but they are fleshy and strong.
The leaf span is 26 inch now:



Another thing I noticed - small green nub at the base:



I think it is a new fan starting...
