I love how diverse your practice is, @Eliza_01- you have explored some wonderful aspects of magick! 
As a very eclectic witch myself, I’d be happy to share some other aspects of magick for your consideration.
I can see you have worked with tarot before, are you interested in other types of divination?
If you are, know that there are so many (and some very, well, interesting lol) methods of divination out there 
. A personal favorite of mine that has a solid backing and plenty of information for those interested is Tasseography- Tea Leaf Readings 
If you enjoy Sigils, you make also find Runes to be of interest. @Liisa shared some wonderful information about Runes in Magick. You can also explore plenty of in-depth rune posts in the forum.
There’s also Kitchen Witchery- aka cooking with magick which is not only fun but tasty as well 
I’m sure others with have some additional aspects for you to explore, and if you’re still on the hunt then perhaps check the List of Previous Spells8 Challenges- as each weekly challenge focuses on a different aspect of magick 
Happy exploring and blessed be! I hope you can find some exciting new aspects of magick to explore
