Sad to say, Neal Adams. There's often a similar comparison and criticism of his peak 70s work with his modern era art style. That said, he can still do some really brilliant commissions.
Has Neal Adams' art changed much over the years? I know his recent TFA cover is reminiscent of his work from the 70s:

Any examples of current work showing his range?
I cant think of any artist's work that has improved after their success. You can throw Art Adams, Mike Golden in there as well..
Actually Adam Hughes is probably the only one I can think of... But he mainly just does covers now so cant really compare
Jae Lee?
Well, I dont think that he is as influential as some of the artists mentioned (Art, Adams, Golden, Miller). Def hasnt been around as long as them
Guess it depends on what you mean by success.
He isn't a legend.
Im surprised that no one has shared some Liefeld & Mcfarlane covers yet.. How can they not be in this thread??
