Cool! I don't got the right pieces, so I won't be able to build it myself, but it looks very good. Very nice creation. :-)

There are a couple of things you need to correct to qualify. First of all, the launcher does not count to the parts total. Only the top itself does. This means your top only has 15 pieces and should be in the light category and not the medium one as it currently stands. Also you need to clearly show it spinning and none of these pics does that. If you fix these items you'll have a fine competitor for the game.

You need a pic of it spinning. Or is it spinning in the last picture.
