One minor complaint, they talk too much. I like MCs during concerts, because it helps you to get to know the girls and because they are fun. However, in a 40 minute festival set like this you just gotta go for it. Keep the flow going. With less talk they could've easily played Shoujo S or something as well.
Personal highlights: Love Survive and Taiyou to Kimi ga Egaku STORY. They really pulled those off nicely 
C'mon, chief! It's part of show biz. You want to keep the interaction going. I betcha the dinosaur was a part of it. If it's a boy band, yeah, I'd yawn and boo them down for being talkative, but for these cute girls, well... I don't mind they talk a bit more as long as they're cute

In fact, I like to see Tomomi talking, it's interesting to see her reactions.
