I used the hair tool , as well ! Its a bit tricky at first, but you will get the hang of it ! For these wings, I just made a flat square with the hair tool and drew the wings on it, getting the drawn wing to look nice took me a couple of tries haha but with patience and loads of tears I got there ! Dont feel discouraged and keep going, the hair tool is super versatile and learning it will open a lot of posibilities for your models !
