Oh, wow, I love their looks. They're both noticeably and notably themselves and *not* like every other depiction of them. I especially love Selina's mouth and nose. She's beautiful, and not cookie-cutter WASP-ish the way so many comic characters become whatever their ethnic background actually is.
If I'm to be completely honest, Ivy was who I thought she was. But I didn't want to say it in case the actual answer was a million percent wrong. Haha. Still, I really like your drawing. Thanks for replying to me!
