Excellently conveys the mood
I'm sure part of what makes this so successful is the music itself - which, granted, isnt one that I understand enough of to be able to translate :) But what I've found is that when you dont understand most or any of the words, the vocal tones and rhythm of the words come out more and can really do a lot for a scene. This is good mood music - and what you chose to go with it worked very well.
As for the style, I've taken a look at some of your other CCC works - the first I saw having been rush 2 - and I really like the blend you seem to have achieved with it, a kind of semiserious toontown with a slight anime influence in the actual art. What I'm curious about is the whole CCC world - you seem to have it pretty well defined. I'd be interested in seeing something that explains some of the styles and themes in the world - but, who knows. Take care, and good job!
