Pretty good, just a few technical notes:
Take out all instants of 'seemed to,' 'looked suspiciously like' and 'floating as if pulled by an unknown source.' It makes your writing sound like it's guessing what's going on instead of what's actually going on. The cloaked *was* pulled by an unknown source, the wall *did* look like a landscape (you can say it looked suspiciously lifelike) and ringing bells of innocent laughter covered the from *from out of nowhere*.
Those are just my examples though, but you get the idea.
I hope to see more from you. :)
