You can try listening to Superhuman Genius, Nerve Growth Factor, Enhanced Brain Hemisphere Connectivity and BDNF before the other audios (or before practising any abilities you’re trying to develop) to help build the new connections in your brain.
Many of the Crystal Kingdom 2 audios may also help development of psychic abilities. Many connect with the third eye, crown or transpersonal chakras. Blue Celestite, Herkimer Diamond and Selenite stimulate the higher chakras but the entire album is great for development.
Schumann Resonance, Moldavite Energy and Quasi Crystal might help as well.
Most cards only last 15 to 20 minutes but you can simply activate them again. Attunement, Chakra Stimulation, Aura Purification and Dreamscape (for meditation and reaching deeper brain states) can help with various aspects of development as well.
The Increase Psychic Functioning tag on Teespring was made for developing psychic abilities. 
You might also try the entire Ancient Arts album in addition to Shen Yang and the new Energy Blockage Removal for energy body development, as developing the entire energy body is important for developing energy sensitivity and abilities.
The Energetic Addendum Est sigils for jing, chi and shen are convenient as well.
Perhaps some form of grounding and auric cleansing regularly as well to clear your system of energetic clutter and blockages. (Aura Purification card, Chakra Cleansing sigil, Automated Grounding, Auric Cleanse, Selenite, Vibration of Creation, Vibration of Divine Love, The Energetic Salt Cleanse or other audios)
Edit: What you’re doing is a very good foundation already!
