The demo was great but a thing that bugged me were the men in the hoods. I believe that they should not show there eyes, as the hoodie men all looked the same. Word of suggestion, please cover the eyes to give the men different looks so they are all unique in their own way and also to change Jungkook's hair. As it should be a light brown with no highlights or blue streaks. (I know they are meant to be glares from the light but they look like blue highlights that Suga has in his hair, so the blue glare should rather be on Suga's hair). Another suggestion is that the characters should have a more realistic face shape (Jungkook looks great however, Suga and Rap Monster should have a more realistic face-shapes and RapMons dimples should be shown more clearly).
I hope you can consider the advice that i have given and shouldn't be taken the wrong way.
I just wanted to mention some suggestions that i thought could benefit and improve the game in the future.
