Currently I’m adding drop shadows to flying objects. What I like the most here is its scalability, as I’ve written about here. Shadows can be everything from simple black circles to realistically casted, semi-transparent drop shadows. To get started I’ve implemented the former:

Further versions could be blurred circles with different radii, depending on their casters sizes. The best quality would be shadows exactly derived from the objects, blurred and displaced depending on flight height and shape-changing according to their casters states. I want to keep it as simple as possible yet matching the overall graphics style. The effort ramps up quickly.
