When reviewing, I always give each category one extra star to the score. Except for newbie writers, who receive two stars.
Writing Quality 5: Very few mistakes. Some missed commas or writing “your” instead of “you’re”, but it still is much better than the average original.
I would only suggest for you to break up the paragraphs into smaller sizes, to make it easier to read. Also, try not to repeat character names so often.
Stability of Updates 5: Personally, I don't like this category, as sometimes the writer needs more time to finish up a chapter, but may end up sacrificing the quality to keep the release rate, so I always give it a 5.
Story Development 4: There’s a problem, which I myself once made, with infodumps. Whenever possible, you should break them up and spread them through the story. If the information isn’t essential to understanding what is happening, then you most likely can leave it out for later.
Character Design 4: A bit early to tell, but for now the characters seem distinct enough, with little to no cliches.
World Background 4: For now, there seems to be a good amount of information about the world.
Review score (5+5+4+4+4)/5 = 4.4
