...yes, I made a pony of Arcade Gannon. They are actually incredibly fun to draw, I don't watch the show, I know next to nothing about it, but I was drawing them and gave into temptation: I google imaged fallout ponies and after searching for a while, it actually seems like nobody has made Arcade as a pony. This had to be fixed, and I kind of regret fixing it.
Also, I forgot to edit the color of the lines, so I may fix the file at some point, or maybe not.
I very much like how the cutie mark turned out.
