No.

No. You have it backwards. You’re placing emphasis on the wrong thing. It should be: “Comparing yourself to me? You’re not even good enough to be my fake,” Shadow the Hodghog brooded. If you’re just using a dialog tag you don’t want that at the start of your sentence. That’s boring. You’re leading with the wrong hoof.

If you’re describing something: an action, a facial feature- sure. Especially if it takes place before the speech. But dialog tags are just to eliminate any confusion with who’s talking. Even any kind of inflection is an afterthought. A means of not repeating “blank says” “blank said”.

Was I seriously dragged all the way out here for this? If I wanted to run a writer’s workshop I could be getting paid for it.
