read very well

You are in a stage of which accent you are simulating to. Since I am learning and practicing a general american accent, I expect r-colored sound and quick t sound from some words which are not there.

The intonation is a personal choice. If you are a teacher, this type of the intonation will help students to understand you much better.

Your voice is very clear, which is your advantage to go forward. You are definitely beyond the leagure of getting inputs from here now with this recording.
