Any tips for making readers care about the characters in a first scene? I'm trying to get some of my stories published, and I know if you cannot get the reader to care about the character in the first scene, you are doomed.
No. You are not doomed. Apologies if this seems rude (I'm merely trying to explain): just like you don't care about a random person the moment you meet them, you don't (inherently) care about a character from the beginning either. You simply don't, unless you have knowledge already of who they are (like it happens with fanfiction, for example).
You could and can make your readers have a good impression of your character/s, but making a step-by-step of this wouldn't help you. It really depends. What you need to do is you take a look at your characters and see if they're likable. What do you like about them? What are their qualities? They flaws? What part do they play in the story? In what way are they being introduced to the story or in what way do you want to introduce them? You must ask this for every single character, including the main one.
You probably haven't written the scenes where you introduce your characters. If you haven't, do it. Then get feedback. If you have, get feedback. Sometimes you need outside help and that's okay. That's what beta readers and editors are for.
