I'm going to assume that the SSSS review was written some time ago as a) the crowd funding for the first book has already been completed and b) Minna has stated that she intends to keep this going for a few years.
I'd say that it is a decent enough review, though in my opinion you are being overly critical about having trouble distinguishing the characters from each other. Then again I suppose art is supposed to be all about interpretation and stuff, so maybe I shouldn't comment on that. I also think you are being a little too vague about why the Silent World is lost to humanity, I understand that you are trying to avoid spoilers, but it is a fairly key part of the series and that knowledge would perhaps draw in people who otherwise would not think the comic worth checking from your review. Overall it is well written, but could do with some polishing in areas.
