In no way am I a super talented artist, but I can give ideas! Goal setting has helped me with drawing (once a day, once a week, those type of goals) and crafting with different materials is super fun! You could try out junk journaling or cardboard crafts!
I would say look at Pinterest or pictures of what you want it to look like and LOGHTLY sketch out a layout as it helps so much with positioning and ideating
Maybe you could try using a giant canvas but putting actual objects on it with some paint, if painting is your struggle. But be confident! Thats really good. I was there about a month ago but i have a no talking study hall so ive been bringing my notebook and drawing. If you restart, what i would do for the people is sketch them out first. When i draw my people i draw a rectangular for the torso, square for the head, and a circle for each of the joints. It makes it easier for me to get the shapes right. Just make sire to fill it out and not leave a bunch of squares and circles
