If you are interested in taking your ukulele playing to another level try one of Choan Galvez’s books of original songs. He’s published a few ukulele repertoire books with The Ukulele Bookshop. And there are more in the works!
Most of his ukulele tablatures are also published on his Patreon site and he recently started his book called “Brevities” and although it’s a bit challenging, the fingerings and picking patterns are well defined in the tablature.
Chaoan is definitely a real find for me!
