Hi!

Great job! Good pay off at the end too. There are a couple of little things I would suggest that I think would really add to it :-)

Try bringing the camera in closer (or maybe start off with your long shot as an establishing shot then cut the camera closer)

Have a play around with speeding up the action overall and varying the timing, you can always film yourself acting it out maybe to get some ideas for the rhythm of things!

Last thing's a little picky but I think the brick would feel heavier if it fell a bit faster

Keep up the good work!
