Vision : It is efficient, straight to the point, but very average and not well balanced as far as the image goes on.
Originality : caricatures are never very original, it's always extremely biased and intolerant by bashing and mocking ppl that the author generally doesn't understand and doesn't want to understand and yours doesn't change that.
Technique : Well the only good point is that it is a caricature and a caricature is meant to be offending to the ppl caricatured, and even though yours is a bit ridiculous and absurdly biased, it completely succeeds in offending the caricatured ppl.
Now technique includes a lot of other points which your caricature fails to be good at : the image composition is unbalanced and boring as it's been said in the "vision" analysis, the drawing is really bad but nearly funny objectively which is what it's supposed to be, the use of computer default font is really a drawback that screams "look I write as bad as I draw and I didn't even try to make it look good" and the lighting, line of force and everything that falls under the composition category is completely arbitrary.
Impact : Now we've got something good, maybe I should just concentrate on the image and how it is built and then I could objectively put another very low grade but objectively a caricature is more than just an image and as a caricature, your work certainly had well more impact on me because of how I feel about this sensitive subject than it should have but still a lot of impact as it is a very powerful debate starter.
