Look, I know i've "kinda" spoken onthis already with certain characters, but alas.
Have you noticed how certain characters lack any ethnic features besides skin color, if that much.
1. Voodoo: I've noted before that Voodoo's ethnicity is oddly ambiguous most of the time, despite her dark skin. I've been told that she's black, but many times you can't tell. This may attribute to Jim Lee's(and many others') inability to draw non-caucasian features on characters. This is especially scary in Lee's case, considering he's....ya know.....not white.
2. Wonder Woman: This is slowly but surely being fixed. I've always felt that Diana should have darker, olive colored skin as well as have curly hair and Mediterranean facial features. The hair was something put in by artists like Perez, but Cliff Chiang has gone and finally given her darker, more "greek" skin.
3. Any hispanic character: Unlike asians in comics, who, no matter what their skin color, can be shown to be ethnic by their eyes, hispanics are a bit harder to characterize. In fact, most, like Jaime Reyes and his family, usually look white unless the artist actually tries. The fact that on B:TBATB, he's voiced by the white actor who played Terry McGuiness/Eric Matthews doesn't help.
I'm not asking for racial caricatures, I'm just asking for more ethnic characters, particularly the women, to look a bit more like their own race and less like photoshopped white people.
