Does this look real?

I spent an hour just adding lines and highlights...and I still don't think it looks real. He wants some real looking ones for some kind of brochure... and now I'm stressing about having 100 plumbers come up my driveway and finding me in my nightie. (I have to make 100 back panel sign for vans... and it turns out I may be applying some of them too).... I lost a client that way once... he knocked on my door at 9:00am and I answered the door in my dressing gown. I don't think tradesmen really appreciate that.
