Sure but not in a deprecating way more of an observant assessment way.
Example of internal dialogue:
"Developed arms and shoulders, works out for looks not function, he'll hit hard but he's probably slow with a poor range of motion and terrible cardio capacity. Toy with him till he wears himself out, strike low (probably knees) and fast."
"He's lean and light, probably fast with stamina but not terribly strong, asses a potential fighting stance (boxing or martial arts), a busted nose will slow him down, go in hard and precise."
"He looks like he might kill you, take out his eyes."
"He looks like fun... let him win."
