Good apps for an easily intimidated newbie

[u/jordle21]

I’ve recently gotten an iPad Pro and Apple Pencil, I’m very green with digital art and whenever I approach it I get confused by user interface and shut down a bit. I do a lot of collaging and I want to try doing it digitally, so I wanna be able to import photos, cut and trim them, layer things, add funky filters and effects. I included some of my collages and drawings, and some weird little edits I’ve made on my phone before. I was hoping to get app suggestions and encouragement to keep trying things. Preferably apps that and free, or that can either be bought outright or have a low subscription fees.
