I'd love to have a blue/bright blue MX Bro, perhaps with a bit of red as the secondary colour. Or a black or gray MX BroBot with blue eyes! I also really liked Ashen.
The recently announced Zombro really blew me away, the detail is amazing.. definitely my dream BroCap.
But really, I'd love to own any piece of Bro's beautiful artwork, no matter the colour. They're all so nice. Unfortunately, I'm new to GH so it's probably going to be a long, long while before I have an opportunity to purchase any of his work so I can see it in person. All of his caps look great in pictures, but I bet they're stunning when they're actually on your keyboard.
Thanks for doing this awesome giveaway guys! Good luck to all.
