Looking good! left a number of inline comments. highlighting one in the middle with formatting since it applies to a number of places i didn't highlight:

just started to notice a handful of [screenshots on the same line as text] throughout the file, do a run through end to end to make sure there's a blank line before every screenshot so the formatting stays consistent

Everything looks great! The writing team will take a final pass in a few weeks and we should be good to publish your blog!
