I assume you are talking about Whisper and Tangle from the sonic universe. If so these are probably pretty close to what I would do!
As for the white haired glasses girl, Toobie, she is based on 2B from the nier series!
😂 😂 😂 I never realized it was 2B from Nier Automata. And thanks how Whisper and Tangle would have looked like human if you draw them.
