Heh
Well I just had to respond to the review previous to this, where you say in New Zealand things are backwards. I live in Wellington, and aside from people wearing shoes on thier hands Rand-McNaly style, guitars work like guitars work in the northern hemisphere. A nice effort to conceal it, I wouldn't want to go back and fix it up either!
The character animation is excellent and the mouth-syncronisation is perfect, top stuff there. Since people of your calibre probably don't need 'oh it's good keep it up' reviews, perhaps you could have some head movement etc. in later flashes as well.
This is all on the grounds that you wrote and performed the music yourself, which is somewhat a grey area as the guitar defies all logic. Even if you didn't it's a great animation, and if you DID then it's a really great animation. 'Keep it up'
