Looking for feedback on WIP classes for a Little Nightmares DnD campaign.

Hey yall. Planning on dming for the first time soon with a group of first time players and cuz I don't have any books on pre-existing campaigns or anything, I wanted to make something of my own. Homebrewing a whole world feels a bit overwhelming (tried it and it did not go well) so I decided that I would try to take a world from a game myself and my friends were familiar with and set the story in that world.

Decided that a great game I could use for this was Little Nightmares since it has a decent amount of stuff and I was pretty familiar with the story. One problem though. In Little Nightmares you play as a mostly defenseless child. You are not the one in power. Cuz of that I felt like the existing DND classes and maybe even the races wouldn't fit. Decided that I would try my hand at creating 5 custom classes. Tried following some templates and tutorials but at the point I'm at so far there's some stuff I'm stuck on. The things I'm stuck on are marked by red sad faces in place of info.

If yall have any critiques, feedback, or ideas let me know cuz I genuinely barely have any idea what I'm doing lol.
On an additional note, I just started planning these out today a little bit ago so I don't have much here. Not exactly sure how to flag this but I'm just labeling it as 5e since Its the only version of DnD I'm teaching myself.
