Robot witch development + secondary character colour redraw

After deliberation Robot witch's final design (above) she still has the gas-like hair coming from an output at the back of her head - the gas appears as the power she is receiving from Gloob. I thought it might be a good idea to give her teal accents to relate her back to the colour of gloobs magic/power. She also has broken wires on her left arm and her hood/cape is removable.

We are still working out how we could give a water colour effect to the background or characters either via paper or brushes.

For Orion, Merv and Sonya I was playing around with colour schemes, Ali suggested to make Sonya look a bit more robotic so I might change her colour scheme + add some seam lines to make this clearer
