yeah, he nixed a plethor of great ideas.
Yeah, have to say there was a slew of great ideas in there that didn't get used, and I honestly think you made a mistake by not showing a wrap.
Even if you didn't wanna use any of the great headlines folks came up with, I think simply replacing all the copy on the left with a picture of wrap would help, you don't need the copy.
Even better, instead of showing your logo, use a picture of YOUR wrapped vehicle with your logo on it (or even use a rendering if you don't have a great photo or want to cheat the logo bigger, etc) then just your 1-800 number and phone number. Done.
This way, there is some sort of reference as to what you are talking about and it simplifies your layout (by combining a picture of a wrap with your logo). Your billboard is still busy and unless someone catches the words "sign" in there, they aren't going to know what you are talking about...I am sure of it. You give people waaayyyy too much credit!
