Shadowdancers are expert in using the shadows to cloak and disguise them, as well as hiding them from their enemies, or their targets.
It’s an unwritten rule, but please try to observe the traditional PnP rules that govern the use of the Hide in Plain Sight feat. For example: Using it only when within 10 feet of a shadow (that isn’t your own). Also, if the Light spell is cast on you it can negate the use of Hide in Plain Sight.
