I was hoping you could do a quote for an illustration of 2 veins. I have attached the image we are currently using. It is not a good resolution and not tailored to us. We need something similar, minus any nerves, lines or the box/close up in the middle. Essentially one vein is less open than the other. The more open vein might have a spiralling arrow around it. I will do a diagram with more info but I wanted to get a rough idea for prices.
For now this would be a still illustration. (In the future we might want it animated, with better blood flow in one vein than the other so it would be good if the style can be later adapted to animation.)
