Another subjunctive question

[tacuba]

Hi everyone:

I'm trying to say, for example to a waiter:

"I thought that I wasn't hungry, but look, I finished all of it."
"Yo creía que no tuve hambre, pero ¡mira!, terminé todo"

"I didn't think that I was hungry, but look, I finished all of it"
"Yo no creía que tuviera hambre, pero ¡mira!, terminé todo"

Am I correct in my use of the indicative in the first sentence and the subjunctive in the second?

Thanks guys!
