I think one of Ross' problems is that he's perpetually stuck in the 70's (except when it's his own redesign of course ). Among the characters pictured, Wolverine, Thor, Captain America, Hawkeye and Iron Man haven't looked like that for some time now. To be fair, his style does lend itself better to the old designs.
I like his work and think he's great on sequentials in things like Marvels and Kingdom Come. His style of realistic looking heroes was fresh and new back then as it played on seeing what those familiar suits might look like in real life. The trouble is there hasn't been much development since then which leaves newer characters and costumes (even some of the ones he's designed) looking a bit odd.
