Zentangle Car Drawing

My summer project is underway--I'm going to fully decorate my car with Zentangle-inspired designs. The final panel will be a full portrait piece  on the front hood. 

Products used are Uni Posca paint markers, both in fine and medium tip, sprayed with a glossy clear coat to ensure durability and fade resistance. 

So far the project has taken an estimated 30 hours, and I estimate that it will be at least double that again before I am finished. Hopefully the weather will hold and this project--first conceived three years ago--will be completed this year.
