Hi-lo-- I am torn beneath the two main mascot proposals; the kinglet is certainly more appropriate for contexts such as the book cover, the conference banner, etc. But I think having the anime character is a great for Ruby as well, and that should be kept as an alternative representation (i.e. not the "official" mascot, but a common theme in images of Ruby and Ruby-related software). After all, Ruby is probably the first language originating from Japan (or possibly even non-European or non-English-speaking countries), and it would be nice to preserve that distinction in its imagery. And just think how many cool variations of ruby-chan would surface... tm
