Nah, it was me who messed up with crappy directing.
I might re-shoot this scene, since the slig simply nods rather than look like he's talking. Also I might re-do the close-up scenes of the green glukkon - There's an error with the skin. It's not so noticeable in the group shots but it is noticeable in the close-ups. That's my fault too, lol. :P
EDIT: Here is the fixed skin which I may refer to later if I decide to re-shoot.
