I like the rigorous use of music theory in the criticism, but I don't think you reeeeeally need those composer references, especially considering that the styles of composition vary so differently. I understand that sometimes classical ("art" music) music has the best examples of a particular compositional technique, but it's also quite possible to separate techniques from content, and I would argue that it is actually MORE beneficial to do so when critiquing.
I think that as a critic, it would be better to frame the criticism in terms of what the artist is trying to do and helping him/her succeed at that objective, i.e. finding those compositional techniques in pieces of the same style and demonstrating why it works or doesn't work for the song in question, rather than simply picking a composer and telling the artist to emulate him/her. It may very well be the case that the technique in question was tried and it simply didn't work due to stylistic limitations, medium limitations, etc.
As an example, why is the lack of a cadence at the end of a song a "mistake" (I just picked the first thing I could find)? Sure, in a traditional classical setting a "fade out" would sound kind of stupid, but consider the context: the song is called "Stars and Skies Forever"! Maybe the "lack" of a cadence is actually the presence of the "fading out" compositional technique designed to question the idea of an "ending", which makes sense because it's supposed to go on forever (according to the title)! So I would caution against trying too hard to fit a classical music context on top of a different style, especially because you might miss ACTUAL things to criticize genre-wise.
And that brings me to my last point: I really dislike the idea of a score for a critique. A score would work in something like a consumer review (in which you're telling someone how to spend their money), but in a critique, scores just feel out of place to me, and it's especially apparent in the VCMG review. You spend almost all your words critiquing the lack of a cadence and the misuse of panning, say that everything else is awesome in what might as well be two sentences, and give him a 9.9/10. As a reader, the dissonance is really striking, considering I just spent half my time reading a critique just to end up at an almost perfect score. It would be better to just nix the scores entirely to focus on critique, imho.
But I like what you're doing here and more blogs/sites doing critique like this can only be a good thing! So keep it up and sorry for the essay
