ReplyDeleteGreat post girls, I liked that you have you own props and you explained them really well. I kind of realized that you didn't memorize you lines yet that could be something that be improved in the next video project.

ReplyDeleteGreat post you Shane. I liked how you acted it out. I really enjoyed it. Next time try not to read off the paper. Other than that, great video you guys.

ReplyDeleteNice post, Shane. I liked how you explained the terms in the video. Next time, don't use your papers too much. Other than that, you guys did a great job.
