This was drawn when I was waiting in the hospital lobby for my medical checkup. I waited for at least 30 minutes so I managed to add lots of details in this drawing. This was drawn without any reference and only with memory. Why did I remember these details? It's because I've drawn this vehicle a thousand times since I was about 9 years old.

The old and weathered effect is just something I did because I had nothing to do anymore so, it's nothing really special.
