This first piece was quite dynamic. Too dynamic, in fact, for the mundane tone of TG. Might make a neat take on an alternate-Earth Twilight Guardian, though.
This one was closer, but she's too young and care-free looking here. At this point, Reza and the gang were supposedly basing her on a combinating of Amanda Bynes, and Hayley Williams from the band Paramore. This is an exceptionally cute shot. It's just not TG.
And finally here's Twilight Guardian as we know and love (and are puzzled by) her. Not as frollicking, but with more going on upstairs.
