Whoa.

Is there any story behind how these came about?

The Puck is obviously so close to AF#5 that I can only assume that the commissoner requested a direct reference to it. That said, any reason for the switch to the 'tights' version?

In terms of the art: Pucks' right hand and the musculature on the left arm are so much better than on the AF#5 version. Beyond that, it feels kind of scary just thinking that the original version appeared more than a quarter of a century ago (shudder). And it also reminds me of the hairy 'PUCK' blurb  (bigger shudder).

As for Eternity: the artwork is basically flawlless here. I respect the figurework, which is impressive considering you're basically dealing with just the outline -- everything is just right. I've never really felt anything for this character and so it doesn't quite give me the thrill of some of the other recent commissions, despite the undoubted quality of the artwork. Still that said, my congrats to the commissioner as the quality of artwork is so high.

Brad, I think JB has commented before that the upside down smile is a neat artist trick to make someone that is upside down look like they're smiling. It kind of tricks the eye.

And, dude, your first sentence: well done, sir.
