You've got the ones I like best already -- I love how Cheung draws Tony (he penciled New Avengers etc.) and also Steve. It's the characterisations as well as the clean lines. That artist succeeds very well at making both male and female heroes look completely gorgeous.

The only thing I really can't abide is some of the 90s treatment with the lantern jaws and mircroscopic noses a la Leifeld. That's just wrong. ;)
