My impressions:
It´s interesting how the "dreams" of the angel are under her feet (unlike in the usual 7 of Cups´ images) They are stored in the tomb like in cellar, where we put things we don´t need now (if ever), but don´t want to give up either. She has gathered human desires but cannot really enjoy them.
The shadow of the cross is only an illusion, but makes her think about the Creator and her own decision not to follow him. She can´t be satisfied here, but would not go back either. Obeying the Overlord would have been as unrewarding as her situation now? Dreams and belief are futile. Is there really such a thing as happines anywhere?
