Alfa-Larawan was invented by Frederick Victor Paredes Añana as an alternative way to write Tagalog. It was inspired by the Baybayin script and the name is a combination of alphabet and the Tagalog word larawan which means picture or image. The appearance of each character was inspired by the human head as well as the mouth & jaw movements. Alfa-Larawan comes in two versions: the Male Version and the Female Version.
Being that there are only two reasonable factors when looking at a script of any kind, aesthetics and functionality, I tend to go 1-5 for both, for a possible 10 for really well thought-out and designed scripts.
This script, I give a 2...that's probably the lowest I could go.
Functionality: When/How would this script ever be written? That is not to say that a written form could/would not develop, but I can only proceed with what is presented, and I see no practicality in this, nor do I see any real use of IPA, X-Sampa, or any other phonetic transcription schema.
Aesthetics: I realize that there is artistic value here, but artistry and scripts can be mutually exclusive, and the former should be born of the latter, not the inverse. I see this as an attempt to make a script from a guidebook on 'how to draw', or some such, not much else.
