Awesome, he's adorable! It sounds like he is doing good, but it would be a good idea to check with bird feed stores about what sort of diet he should be getting. Some birds, like my Mother's Macaw, can (and should) eat almost anything, but others might have a hard time on an unusual diet. Also, keep an eye (bad pun, sorry) on his eye in case it gets infected. I don't know if you feel he is worth a trip to the vet, but it might be a good idea,
