How can i make these wings?

hi, i’m wondering how to make these wings, do i have to use any modefier?

what do you mean? do you mean you want to animate it?

how can i model them, i don’t know if he’s extruding because it looks too smooth.

yes. you need subsurface modifier for it to look smooth. and crease the edges (or add loop cuts) where the look sharp, like the corners
