It's been a while since I saw this piece. I wonder if your ever planning to draw more X-Men art. I'd love to see X-23 get her revenge on Kitty. Particulary if it would involve her stabbing Kitty's eye sockets out. Bitch needs to learn not to mess with X-23, hehe.
Either that, or you could try a stand-alone drawing of X-23. I love your art-style, but I must admit that I dslike how you drew X-23 here. Her face looks very odd here, it's almost cartoony. It's almost like you intended to make her look like a mockery.
...Actually, how DID you come up with this idea anyway? X-23 vs Shadowcat...These two never even interacted before.
