Thanks for the chapter. Regardless of what you were testing, it was readable enough that the only big mistakes would be, as other people pointed out, if you unknowingly mistranslated the meaning of a sentence.
But in that front, most of it seems consistent with the rest of the context in the chapter, so most likely you shouldn't have more than 1 or 2 bits with that, if any at all. The grammar could be improved, but it's perfectly fine for people with decent enough skills in english.
Rather, thanks for taking the time to both translate, clean and typeset the chapter (or at least doing some of those, if you found translation or clean raws somewhere) and putting them up. It is greatly appreciated, and looks great IMO.
