Welcome to the forum.
Really interesting to hear what native speakers have to say :)
Your accent sounds to me like that standard flat American accent and had you not disclosed your background, I would probably say that you were raised in a bilingual family. But I have just been in the US for two years and cannot claim to be an expert at this.
Out of my interest, at what age did you move to the US and how many years have you lived here?
P.S. I like to read about this wonderful state of Arizona.
