Arrow conceptual artist has posted concept art he illustrated for Speedy and Katana's costumes.

In the Season 3 finale, Thea Queen (Willa Holland) became Starling City's latest costumed-vigilante. Her costume is a modified version of Roy's Arsenal outfit and she'll operate under the childhood nickname her brother Oliver Queen (Stephen Amell) gave her, Speedy.

In the 22nd episode of Season 3, "This Is Your Sword," the sword-wielding badass Tatsu Yamashiro (Rila Fukushima) made her first appearance in her Katana costume.

Check out the concept art below.
