I almost never do fan art, but I'm challenging myself to draw a ton of G.I.Joe this month. Starting with Scarlett!
I didn't really do anything crazy, just my own detail pass of her classic costume; leaning a bit towards influence from the Resolute design. I give her a Mk23 because I thought she could use a sidearm with some heft to balance out that crossbow.
For the crossbow itself, all I knew was I wanted to imply it was charged by a battery, like it primed some sort of electric bolts. As for the bolts, I imagined them loaded by stripper clip straight into the back of the stock there, and the next bolt is lifted up a small slide when the pump is pulled back, then pulled forward into firing position when the pump is racked forward.
