Okay, so something I've found is that the layout of the contents of the panel is always more important than the layout of the panels on the page (or scroll).
Clear visual storytelling, done really well, will always look better than a bunch of fancy panels with people breaking the borders, extreme closeups, weird diagonal panels etc. I learned that reading the original manga of Fullmetal Alchemist. That manga feels so intense and dynamic to read, so I was like "Aha! I'll study Arakawa-sensei's panelling!" only to realise... it's nearly all just basic rectangular panels! Same thing with Naruto! Rectangles!
Focus on what's in the panels. Try to add some depth using foreground, middle and background. Put things on a diagonal, rather than straight-on or a flat profile if you can. Don't forget to raise or lower the viewpoint rather than always putting it at head-height.
I can already see you're implementing the right techniques, putting in a nice variety of over-the shoulder shots, wider shots and close-ups. Keep doing that, and experiment with raising and lowering the camera to add dynamism and show power-dynamics or context within a scene. Try studying stuff with good storyboarding. Some of my favourites are the Scott Pilgrim comics (extremely dynamic, but also very clear), and shows or movies like The Incredibles (watch it with the commentary on, it's so good!), Arcane, Mad Max Fury Road, and anything by Alfred Hitchcock. Try to pay attention to where they place the viewpoint and absorb that wisdom. If you've read "Making Comics" by Scott McCloud, read it again, and if you haven't read it, go read it! You might also find "Drawn to Life Volume 1" by Walt Stanchfield really helpful at your current stage of artistic development!
