Welcome !
Maybe it could be cool working with the elements on different planes. There are the classic GD aura exercices: the one with the 4 elements(i know, i will, i dare, i keep silent), the middle pillar... you can do similar stuff with Nuit, Hadit, Ra-Hoor-Khuit. And maybe try to apply the elements within your life and activities. In sports, intellectual matters, arts, relationships... know well the elements and alchemical principles, and how they interact from one plane to the other. Also repeat the basic ritual formulas(elements, lux, nox) and feel the differences. Do all both on physical and astral plane. Feel the interaction between physical and astral. Make the astral as the physical, and the physical as the astral. Meditate on all these things and a lot on the tree of life. Do pathworking. Have fun ! 😄
