Blackjack faces the one monster she cannot beat - the Crusader's trade master and soon-to-be richest pony in the Hoof: Charity! Fallout:Equestria is courtesy of the great Kkat, Fallout:Equestria - Project Horizons, Blackjack and Charity are courtesy of the not-less-great Somber.
I used a lot of artist's liberty with this one, as Charity is never properly described aside from having a yellow coat. I thought the light blue mane and Sweetie Belle-ish mane style fitted her well, as well as her Bottlecap cutie mark.
This drawing also marks the first time I *ever* drew a background, so it naturally looks a bit wonky at plac--- I mean everywhere.
This work was created with the Painttool SAI and a Wacom Bamboo tablet.
/update: Thank you all for your kind words and helpful criticism. I updated the picture and made a few minor changes: The bad angle on the upper window bar is corrected, the grass is notably darker, I added a few more curls and highlights to Charity's mane and I severely shorte--- ehm, *compacted*, Blackjack's horn.
