well if you're asking if there is more content - there are no additional rooms than the ones visible on the images. the room of requirement (big hall with pillars and loads of junk) and chamber of secrets (with the big statue) are accessible only through teleports. except these two everything else is accessible on foot and visible on the main panorama image.

otherwise "inside" is mostly limited to main hall, gryffindor/ravenclaw/slythierin dorms/common rooms, magical grand staircase, library, various classrooms in the astronomy tower, kitchens, greenhouses, hagrid's hut

second jump is preferred but not strictly necessary. mounts will fit in most main passages but not everywhere. a lot of rocket boots, wings, flying mounts may actually lead to worse experience while exploring - as the spaces (especially "outside") are actually very confined and some of the "background" structures are actually made of blocks
there are some teleports to make moving around easier

can we walk around in this map like can we go inside?

thanks!

really great map, enjoy
