The first one would go into my "nearly brilliant" category - had you caught the aircraft as it passed the umbrellas, I think it would be fantastic - as it is, I'm afraid the composition just doesn't have a focus. I'm sure if it were mine, I'd be tempted to upload, but objectively I don't think it works.
The banding appears to be due to OVER illumination of the Nikon's LEDs. The only explanation I can think of are faulty LED's, though these are pretty much binary devices - they work or they don't, or some kind of problem with the power supply ... surging? If this is the case, I would get it serviced pretty quick, as it could lead to more serious (and expensive) damage.
