I think you've gone slightly too cartoonish on these entries. If you pull back a little bit however I think you'll reach my vision slightly better. I dislike the solid black background. Doesn't mean it can't work, but as of now, I can't appreciate it. I envision something a little more slight, more subtle. As for colors, I think you have pushed it too much. I really want to try and stay within the blues a little more. I don't mind have a large palette of colors, but blue needs to be predominant. Like as in entry #17. To date this is my favorite of your 5 entries.
Think less, audio (or heavy bass) coming from a supped up Honda passing by a few streets down. Think more, a refined audio sound track that can better a well known feature film that is bound to win multiple prizes at a film festival. Subtle.
