Trenly, the map would look better with isles of bookshelves, rather then just a square room. There is little to no detailing on the walls. Only books, and the parkour itself stands out a lot. Like
Trenly said, Jigsaw is meant to be a puzzle. If you've played Prison parkour or the 2016 Christmas lobby parkour, there are puzzle parkour rooms in there. (Rooms where the rout of the parkour isn't necessary clear, so you need to try and work out where to go and how to get to the next room)
Also, the glowstone looks out of place in the last room.
What you've done:
Still no bookshelf aisles. Still a square room. Still no detailing of the walls. The Parkour itself still stands out a lot. Still no actual 'puzzle' to it. The glowstone does look less out of place, that's basically all I can say.
