It's fantastic like always Eduardo ! (is that UK client btw.. ?)
One suggestion/question: I see the reflection in first image in glass as unnaturally strong. Is still result of you rendering against black background ?
If yes, I recently found that I first overlay white in Photoshop from alpha channel mask, flatten, than use alpha mask again, so I get both benefits,
clean AA with no outline from black background, but correct intensity of speculars in refractive surfaces.
But if it's intent, then sorry ! Just looks like issue I dealt with recently.
