I heard 2 audio records of yours. Basically you did your work well, I can understand you and I can guess all of words you spoke. However, I think you need more time to improve your Vietnamese accent and there are some words need to be corrected such as: tiệc cưới, của, nhiều, đến, đều, tuần; chuyên kinh doanh... I can help you practice through Skype. My Skype nick is in my message sent to you (friend request) few days ago, see you!
