A concept that was created through the ingestion of far too much coffee and not enough food.
This is Lady Karla and her giant mech Ser William. Ser William was the robotic butler in her house and raised her as her parents were usually out attending social functions or fundraisers. When Civil war breaks out the lower classes go after the upper classes, slaying them in the streets and sadly her parents are killed. She inserts the AI of Ser William into this mech and they travel the lands with Ser William as her shield. And a gazillion guns.
The smaller image was a quick speed paint of Karla although the design deffo needs some work. Got a trial version of Corel Painter so let's see what this baby can do...
