Cosplay help

hey as you guys know from my intro post, i do cosplay. I was asking if any of you would mind offering some advice for new cosplays, first timers, or people who just wanna get to know it. As for me i can help out a bit, mostly with props as that is what im better at, but i might be able to give some tips in general. i was gonna ask you guys if you had any tips to do this cosplay.





Now i need to choose whether i make the sword or the claw. Claw would be harder to make but with sword id have to walk around "without an arm". Any tips on how to make the rest of the parts?
