Here's the thing about that. And keep in mind, I'm really biased; I think I win the award for "biggest Adam Hughes fan", and it colors my opinions of stuff. But here goes:
There's a reason we all like Adam's art. And there's a reason he's one of the top comic artists of our time, and many consider him to be among the top illustrators, comics or otherwise. And that reason, besides technical excellence coupled with a wit and intelligence behind the work, is that ethereal something.
Is it a smirk behind the eyes? An elusive tilt to the head? Something inviting in the posture? I couldn't say. And I look at alot more Adam Hughes artwork than the average bear.
Some of the most talented sculptors out there today have had a turn at working on Adam Hughes designed and inspired sculptures, and we've yet to have one that everybody agrees captures Adam's art perfectly. Why is that, do you think? Is it because the talent working on these projects is inferior, or is it because Adam's art has a quality that resists being captures, a quality that continues to make Adam one of he best in his field?
Just my thoughts on the subject.
