Since I was so impressed with how spot on Sailor Moon Crystal was to the original manga, I decided to create a gallery with side by side comparisons. Manga scanlations by Miss Dream.

I just noticed, Crystal seems to avoid having Usagi do smiley faces a lot. It's a shame. Would have liked them to animate this part where she is like "TUXEDO KAMEN <3" and Luna pulls her by her pigtail to get home.
I like how they actually made Usagi squish her face against the window of the shop, in Crystal, though, eheh. She's so cute

Since episode 1 was so much like the manga this tells me that there would be a good chance that the bus scene in chapter 3 and the way Usagi found out Mamoru's identity will be kept similiar to the manga.
