Here is the updated idea for my final design. I think for now I would like to keep the horse drawings greyscale, as it is still possible to represent colour this way, and I would like the writing to be gold. I have choses gold because it reflects on of the most used colours in horse racing, and also adds a sense of grandeur to the piece which should match the impact made by the size (I would like to print it as large as possible so the conformation and difference between each horse can be seen clearly).
