I went through yesterday and was underwhelmed.
I actually don't think it is any better than the original lounge. They have tried to apply the Galleries concept but I get the distinct impression the current financial state of BA means costs have been cut.
It just feels like a big internal space with no character whatsoever. The lighting is terrible - no natural light whatsoever and the un-natural light is is horribly bright.
Apart from the furniture there is nothing 'Galleries' about the place - where are the horses!!!???!!?
I think the only improvement is the crockery.
