Collaboration for Sketches

I started a collaboration with a Spatial Design student, Helen Middleton, as I really liked her style of drawing and asked her if she would be interested in doing some sketches for some of my images in my app. She started by doing these factories in my original colour palette.
Because of her own assignment, Helen didn't have time to do anymore sketches for me, however if I was to continue this project and develop it further, she has let me know that she would be interested in doing more of the sketches so that the visuals look cohesive.
