Love the Raven costume, very classy and reminiscent of her original outfit. I like the leotard & "elf" shoes she wore in the cartoon as well, more practical than a dress and high heels, but the old look still works as well, sexy yet mysterious and elegant...It also depends on whether Raven's gonna be very active or stand or hover in place while using her psychic powers...Cuz in real life running in high heels is near impossible after all lol.
Robin's armor looks badass, I see ya went with Grayson's Young Justice colors. I like Deathstroke's outfit as well, though I miss the chainmail/scalemail that was incorporated into his and Rose's old costumes, made them look like a cross between ninjas and medieval European knights (I don't miss the orange shorts though lol).
Kid Flash looks cool as well, no issues there, though is that supposed to be Superman or Superboy wearing a costume more akin to his gene donor?
That would depend on the effects and not sure what way the director wishes to go yet. But I see your point, high heels can be hard to run in. Though miraculously I've been able to do it sometimes. (Normally don't wear them though) Not sure if they will go the classic route or if they are going to do the version I shall be posing up later.
That is actually one of the older versions of the outfit for Robin in this picture. I see what you mean for Slade, that could be because of the person who is wearing it. Really depends on preference. Honestly exactly how costuming goes depends upon our donators. The more we receive the better the costumes will look. In fact the majority of the budget goes to costumes. Once we have those it will be extremely easier to film. Then you could say we would have the ball rolling.
For the Super, honestly I think it might be Superboy prime or superboy but I know this isn't likely the version they will do if Superboy. (I would have to ask the team)
