Your sketches are amazing. I love the combination of line, value, and textures. The forms you’ve created are profound and definitely memorable, and definitely read as an electric car, if that is what you were trying to communicate, great!
One area where I definitely think could use improvement are your arrows and writing. They are too powerful and have so much contrast that distracts from your beautiful sketches. I would have liked to see “sketchier” arrows with handwriting if you do indeed need to communicate something with writing.
