For MC, high button stance sport jacket and low rise pants leave him with a blue navel triangle which is far less than flattering. The pocket square needs to restrained a bit more. Otherwise it would look far better with more tonal contrast between the trousers and jacket; e.g., a jacket of opposite pattern or light blue check on navy, or charcoal trousers would pull it together. Finally, replacing the surcingle belt with a leather one, would make the sport jacket look far less like an after thought. Navy or even chocolate hopsack blazer with lower button stance probably the best choice to upgrade the outfit with just one fix, otherwise a leather jacket bomber would much better.
For SWD. the logo on the T-shirt greatly lowers the sophistication of the look. Black or indigo jeans would have been the better choice as the trousers look like they were the only clean ones around. As above, a leather jacket would crank out the style points, if black were it's color.
I see both of these looks all the time, but neither is worth a second glance or remarkable other than they are average looks requiring no thought other than what might be clean at the moment. In fact, that is the message; "before I ran out the door, I grabbed these clothes off the peg".
