Everything I was going to say about it has already been covered. Evaluation of an alphabet in absence of how the language is spoken (or if the written language even resembles how it is spoken) is probably a fruitless exercise. This looks like a alternate alphabet for the English language, but if it's not then in order to evaluate it we need to know how it is used.
I wonder is anyone has even come up with a unified alphabet able to represent all of the sounds that human language uses.
