You don't know even half of it, lol. That guy is supposed to look like a decrepit old dirty peasant or pretty much a beggar, with a very slovenly appearance, teeth and mottled sword. Like a peasant so dirty you wouldn't want to buy the stuff they try to sell at a roadside stall because the guy is so filthy. That's what he looked like in the novel and it was mentioned multiple times.
Why does he look like a muscular wanderer here? Kinda disappointing. At most slightly yellow yet perfect teeth and some clean but slightly patched clothes...
Seriously, what's up with the artist of this altering the characters appearances and ages, sometimes even race and gender, not to mention the story itself. Lost count of how many times he's done that already.
Would've been cool to see such a decrepit shabby looking old bastard with food residue in his teeth as was described in the novel instead of a wandering swordsman kind of look.
