Hey there! I think you ended up at a good (and really fun) resemblance. If there's anything I might suggest, I might push the length of his nose further until it's pushing down on the mouth area (if we're thinking about the face like a lump of clay with mass to distribute around) since it sticks out to me as a prominent feature and you already have the mouth region clustered low. You could also push the proximity of his eyes and eyebrows together, as even in the picture they appear grouped together in shadow as the brow bone protrudes forward.
