Finished the linework a very long time ago, and finally did the colouring yesterday. They're both blankflanks in this drawing as they're based on their characters' portrayal in Friendship is Witchcraft.
I based the robot design for Sweetie Belle(Bot) on Time, Love and Couture's video here. His sculptures are really amazing, go check him out if you haven't already! :D
I post my art over on my Twitter if you'd like to come say hi!
