Yes, Iberian spanish. The issue is that I'm from Latam, so the slang used in Iberian spanish, and some conjugations still sound foreign to me. In english, King's words flow better, the intent and the idea are much clearer, and since I've been much more exposed to American culture than Iberian culture, it feels much more familiar.

Ah, I'd guess the Latam Spanish has more traits in common with the American English. Similar to Iberian Spanish novels being compared to the British English ones since Cervantes/Hamlet.

On these conjugations, compound verbs are not hard at all.
