I like it! Good to see a clear disc being used for the spinning prop, rather than those 'static' pe blurred prop thingies. The only time you'd see blurred 'static' prop blades is in a photo taken with a moderately fast shutter speed, so the disc looks much more convincing.
If you're able to mask the disc, leaving just the outer peripherary visible, a thin, translucent coat of yellow would really finish it off.
Nice work Dirk.
