We wanted to create a fun card that incorporated some of the things the tour guide liked--specifically cats and his motorcycle. I saw his motorcycle and had an idea of how it looked, but wasn't really trying to do an exact copy. I did some online research for Ducati motorcycle pictures and did a sketch first. My sister drew the cat and once we got the main parts down, we positioned a fresh piece of paper over the sketch and traced over our sketch. Not having a fully functioning eraser and not enough lead in the mechanical pencil made it challenging because we didn't have a chance to redo our marks and we had to work with a pen for drawing.
It took a lot of time for us to complete the card, because we ended up drawing a background and then adding shading. However, we had fun drawing the cartoon and the tour guide appreciated the card as well.
