Any sons of Lilith want to answer this for me?

What's the difference between the entity connected to this sigil...

This insignia appears like that of the single key sigil in relation to her true throne sigil, but it is altered. I don't know the origin so without its true meaning an observer can only witness and speculate. To me it seems like a personalized symbol of some form of worship/following of her. It could relate to her true sigil or be personal to the person who created it, or it could be something they made up and there is also the rare possibility that it could have been given to the creator by the Dark Mother or by one of the lilin. 
I think ultimately the importance of it itself as a symbol is redundant. She is a goddess who connects very personally and intimately with her true followers and ever more so with her children. If you desire to connect with her you'll find the path as long as you look for it and approach it all with honesty and an open mind.
The second sigil is Lilith's sigil, her main sigil/symbol/callingcard for lack of a better term. It is similar to a gnostic/goetic breakdown of an entity and their title or name. This is a symbol I find is closely related to her in connecting or channeling her.
In the following of her, she will give you inclinations toward pure connections like sigils, other magickal practice, music, cinema, whatever will essentially entice you and help grant you the understandings you need to help you continue your journey.
