I listened to the first part a while ago so I'm gonna miss critiquing some of the roles outside of the mains, sorry! DX
Chloe: You did a very good job at emphasizing her awkwardness, but I think you took it slightly far at times, exaggerating a bit too strongly and bending some enunciation as a result. Perhaps toning the acting down to get the subtleties would work for you in the future. Nonetheless, you displayed a whole range of strong emotions and carried out a lot of great, nervous energy. Quite worthy as the main lead.
Kevin: You definitely have a good tone here; you have a very natural sounding teenage voice. I really like the low drawl in your voice because it gives me the sense that he's laidback and honest. However, I'm not sure if it fits the character at certain points. You sounded tired or bored throughout; adding some energy to your lines would benefit to give a little more variety to your performance.
Jessica: I wish she was my best friend... ;A; Really, I love how gentle and wise you made her sound, yet full of wit and playfulness woven into her low-key tone. You made her sound both mature and supportive, and your performance makes her one of my favorite characters in this radioplay! :3
Gray: Wooow, delivery was extremely natural. I love how casual and fun-loving you made him, with all the little quirks and acting full of life. You gave him tons of personality; if he was real I would wanna chill with him. XDD Unbelievably believable! 8D
Lydia: I expected Lydia to be rather peppy, but I'm glad you didn't turn her into a ditz! You made it so that she was just a really nice, smart girl, and you laid out her modest personality quite well. A bit monotone at some points, but I liked how you portrayed her shyness. Good job~
All the minor roles and extras were really well done and placed. This is a great slice-of-life story, with a well-written script brought to life with great actors. And of course, good morals are thrown in here. Tara's last line in part B kind of tugged at me, because it's something I had to consider before too, heh. So, for me it was easily to relate and connect.
Mixing was fantastic! The ambiance and sound effects blended together very well to create a believable setting; I could see this out of a movie hehe.
Overall, I enjoyed this muchly~. Good job everyone. <3 Looking forward to the last part!
