Things I guessed correctly:
-Announcement before summer-check
-Knight Bus marking entrance-check
-covered area--wrong location and purpose, sort-of check
-Location of WWW down from Gringotts--Check (Film Location, also used by Voilarum in his artwork)
That's a Bingo!
EDIT:Looking at some of the doorways, structures, and such this artwork probably takes some liberties and depth-based alterations. It probably only looks like the Pottermore version is because it's artwork and therefore looks more colourful then the street in the films, and is wider because of people traffic.
