When Rob switched from X-Force to Image Comics, he knew already he was a superstar and he knew what made him popular: shoulder pads; giant guns; grotesque biceps on men and barbie-to-the-extreme women; "angry eyes". Looking at those above, all of these things are taken to the even more extreme.
Rob's "Brigade" and "Bloodstryke" are the comics that had the most Wolverine and Cable copies, but you can still see similarities here. Chapel is basically a black Cable. There's Domino on the cover. (To be fair, Rob created Cable, Domino and Deadpool and was angry he would never get royalties for them--so he basically copied himself and started over).
The side (A) cover isn't all that bad and like Lash says, shows a somewhat still restrained Rob Liefield that was still trying. Side (B) however, is just over the top and here we see a young Rob realizing: "I have no editor; I have no art director; I'm my own boss! Jillikers!". The dude on the left of the back cover is so grotesquely over sized that I can't decide if I want to laugh or vomit.
On Side (B), take a look at the guy running towards you. Snapshot in your mind that pose. You will see it over and over and over and over again. Rob still uses it to this day, repeatedly. He must have a pic of it on the wall in his studio and just copies it.
Something else else we need to remember is the real criticism of early Image in general was the story. Only Rob had the double-whammy of heavy criticisms on his art. Chapel, within, is a full-on serial killer. I think its implied he's been a rapist at some point. The troll dude typically decapitates people in battle. It was a rough time for comic books. (Let's remember, Shatterstar was already chopping off people's limbs in X-Force via Rob, so Marvel helped kick this off).
Now recall a specific factor: Rob was the best-selling artist of the entire 90's. He made MILLIONS. I'm quite certain, he never has to work again. Incredible.
PS - one thing by Rob that I liked? The Image "i" logo. That was nifty and designed by Rob in a pinch.
