I really love the dramatic lighting you use - it adds tons of emotion and with the way you draw faces it compliments amazingly well. Your panels are composed in pretty fun ways so far, too! The poses you use are expressive and lively.
I think one of the things that stands out to me is the fundamentals - sometimes your colours go outside of the lines, or your linework feels a bit shaky! If you focus on reigning in that lineart your work will look much more lively and fluid. I think increasing the stabilisation of your brush should fix that. For the colouring, just be extra careful not to leave the lines.
The biggest thing is the panelling. Some panels are full of energy in their content, but the panel itself is a flat rectangle. I think being a bit more experimental and daring with the shapes and sizes of your panels could help a lot - try using diagonal lines to separate two panels where characters are arguing, to add a bit of intensity for example. Try long and stretched out panels, isolated panels, spaced out panels... Maybe try circular panels, or panels that slot together in fun shapes. Mess with it and push the limits!
It's definitely got loads of potential and you've made a good start on it.
