I'm making the same cosplay :) How do you do the arc?

The arc? Do you mean the bow?

I used two layers of EVA foam (think floor mats for garages or yoga, you can get them at most hardware stores) which I plasterwrapped and then gesso'd. After it was dry, I sanded it down, drilled holes for the string, and painted it. I used a short piece of PVC pipe for the grip and covered that with fabric.

In retrospect though, I would probably have used worbla if I'd known how to use it when I made this cosplay. If you're willing to shell out the money and have a heat gun handy, I think it would be worth looking into it. There are also a lot of tutorials out there to help with worbla props. I'm just now learning how to use it myself, but I've been super happy with the results.
These are photos on my cosplay page that have worbla pieces if you'd like to see how it looks!

Hope this helps!
