For arty I used the first m.u female bulk, her details were sculpted and her quiver is from a yj speedy, as her head is from a yj black canary.
Wally is just my last Wally with a new symbol and head changed a tiny bit.
I am not a giant fan of either of them but they are just getting rid of spare peaces really. As I really dive into doing dc in mu style arty will have the new body and Wally will have a Steve Rogers body. Arty will also not be g.a then she will be tigress.
