Color discrepancies aside, this is an EXCELLENT rendition of Blackjack. Personally, I like her better than Littlepip. Nothing against Littlepip, though; I just like how deeply flawed and tortured Blackjack is about her past, and how she tries (and often fails) to overcome it.
Now, is this pre- or post-cyber Blackjack? I ask because of her lack of a Pip-Buck.
one minor nitpick, her magic is white and her eyes are red, with the whites of her eyes being orange (or red and white, if you want to go for pre-radiation sickness). aside from that, i really lock how this came out.
