Yes, there should be 3 rolls on the sleeves instead of 2.
The only things I would note would be the ribbon on the collar looks a little off because it's shiny (I'm assuming a satin ribbon?) while the rest of your costume is matte, maybe you should consider using bias tape instead to get a better look.
Also your bow is a little droopy, you can fix that by tacking up the corners of the bow. And the 'v' in your skirt should be shaped more in a 'v', it looks like it's straight across ... maybe it's just because it's on the dressform?
Other than that it looks great! I'd love to see the boots and gloves ^_^

That's not Sailor Moon, that's the the other Sailor Scouts, that's in Super S, where Sailor Moon becomes Super Sailor Moon, and she has completely different sleeves and skirt.
