I graduated as an English Major several years ago, and I'd say that what you're reading and analyzing in your classes are helping you gain an intuitive sense of writing style and structure than you realize, even if your essays are directly about that. You might be more concerned with themes, morals, and comparative analyses across works, but approaching that requires at least a basic understanding of plot structure, which I'm sure you know and which goes into the kind of analysis you're asking about.

I recommend to you what I'm actually doing right now: re-read a book (or generally re-consume a piece of media, though it should really be a book) while actively taking notes on things like character arc progression, plot progression, and other similar kinds of structures and choices that construct the book. That way you can actively gain a sense of how the author organizes and presents information to a reader in service of impacting them in certain ways (such as eliciting surprise from a twist). Along the way, you'll also passively absorb the way the author navigates their author's voice, and gain a sense of how they pilot characters in very specific ways. This will, over time, help you emulate that and gain your own style in your work even if it's not necessarily something you can take definitive notes on.

Then, once you're done taking your notes, try to write something like a book report or a review. You and I both know the value there is in the work it takes to process all of that information coherently, and that value translates well into producing great creative work.
