Ok first off. Love how your keeping up with the story. There's not many stories where Ruby gets stuck in another world by herself.
Second. I think you should go back to the beginning and add a little more detail and background on just how Ruby got the DC YJ world. That way its not us wondering why and put a little more emotion in how Ruby reacts.
Third. You got Qrow down pretty good in my opinion. Even at the end where Black Canary losing the fight against him due to his Semblance of bad luck.

Really over all. Add a little more supportive emotions and facial expressions to your people and this story would be five times better. Keep it up.

I think that you need to continue this story

Qrow's arrival is really well done, but it feels a bit early in the story.

"Ruby why is there a blue you?" XD Seriously though update this soon that was hilarious I like the premise as well (Saphire's an interesting addition ) and while there are many ones where characters of other worlds end up on Remnant, there are not nearly enough stories of Ruby ending up in another world..

It's a good story and I like that you are now quickly updating the story but you should put more into the story because they are really short and it doesn't help you put the last paragraph from the last chapter.

Honest opinion, me myself and I like it but yet at times it feels rushed. You might want to slow down a bit, take more time to explain or describe the events taking place to further expand the story.

How the heck did they get her dna

Really fast paced. Slow up on the frame by frame stuff and a bit more back story and this will be great.
