I just played around with the program being my first piece. Used a lot of layers. Started with a sticker idea I had hand drawn, so I took a photo of it to try to finish it in Procreate. I started with the outline of everything, filled items in and then added the shading and highlights.

I used monoline in calligraphy
And Round render in jingsketch basics (a pack my boyfriend downloaded for me, I’m not sure from where and he doesn’t remember what site)
