A lot better! Try to feel vibration in your throat (=Kodama booster) the whole time -- even between words. Your English will be a lot smoother that way! If you can feel vibration, it means your throat is relaxed.
You are doing a great job! I just wait to call you "a domestic native" till you are done with the whole book. Just keep trying to reach the deepest area of the throat as you practice.
You are really doing very well. Your a_ is great! Work on i_ (e.g., fish), E_r_ (e.g., work), and v (e.g., conVinient) though.
