well surely, your art is definitely evolving/changing! it's texture sort of changes as time goes by.
but I'm gonna be straight with you and say, i'm feeling it has that sameyness to it, or well, at least with the images you've shared, it feels very safe (I feel like some people might not get that line xD, in short, "safe" is when the art doesn't do anything spectacular or experiment, but as a result it never really screws up either.)
this is because the panels seem to emphasise a little too much on the back and forth sort of face exchange :u
if it were me, I'd like to see more ways to mix up character exchanges more, like having them emote with their body (because I cant stop talking about the art of "gesture"), and using shots that don't emphasise the face as much (unless the facial expression changes drastically, then another face shot would be nice), that way you don't feel claustrophobic during dialogue exchanges (unless that's the intent!).
outside of that, the color choices and facial expressions themselves are fine! do keep up the good work on that front!
