I think its to do with the subject of the sentence.
The subject of sentence 1 is happy accidents, and he is describing it as a ‘happy’ accident because its turned out in a pleasant way, as opposed to something like “frustrating little accident”.
Sentence 2 the subject is angry intent, like he is behaving in a way that is focused by angry emotion, and in this case ‘big’ is the modifier that is giving you a scale of how intense the emotion is.
Note: I am in no way an english or language authority, just how i think my brain is handling the structure of those sentences and the order that feels ‘right’.
