Agent Brown - if you look at the picture, it looks like he's the kind of guy who has a lot of money, ties a sweater around his waist, plays tennis during the weekends, drinks out of a champagne glass a lot, but is kind of a weakling. He also doesn't have the physique of a figher. For short, he looks like the typical, richboy yuppie kinda guy who may even talk with an english accent.
Agent Jones - He looks like someone who could be a bouncer in a club. Just look at the face and the height! YOU DON'T WANNA MESS WITH THIS GUY!!! You don't!!! Look at him!!! He's the kind of dad you don't wanna have if you come home later than agreed upon. Looks like a strict dude, if you ask me. Once again, don't piss this guy off or you're going to regret it!
Agent Smith - Unfortunately, Agent Smith is the nerdiest looking out of the three in this picture. He looks like the weakling nerd the bullies would beat up so that he'd do their homework. He also kinda looks dumb like he has nothing in his mind (especially with how he's clenching his jaw). Another reason why he looks like such a nerdy weakling is how "small" he looks compared to the two. He even looks like he's being ganged upon by the two other agents, especially since he's in the center and kind of far off from the foreground.
heheh...well, there you have it ^_^! My analysis of the 3 agents according to THAT PICTURE ^o^!
