To make myself the entire arm took me practically one month. But also it was the fact that I sometimes did not have a lot of time to follow it. But if you propose it, I assure you that in one or two weeks you achieve it ^^!
Haha, thank you! My con is the week after this and I know there's no way I would be able to make one in that short amount of time but just for future cosplays I'm curious ^^
