Very wrong. The vortices from the motors form the angel wings.

I was texting of the "green globs" and also the color inconsistancy (dang I learned a new word lol) of the smoke on the left hand side and the right of the "wings". But you do have a valid point. :) Either way , it's smoke lol.

Actually, it's wingtip vortices that are controlling the shape of the flare smoke. Note the location of the tight curls. They can be traced to the wingtips.

Wingtip vortices from large aircraft can be very powerful. This is why a small plane doesn't immediately takeoff after a large one. You take you time to allow the big guy's wingtip vortices to disperse, and you don't lift off until you are beyond the point where the big guy did (assuming the runway is facing into the wind).
