I see on your website and facebook page that this is your logo. I think it could stand a rework, but getting that past the boss man is going to be some work. The tree is unnecessary, the background is very dated, and the grid pattern and fade from wireframe on the tree doesn't translate well for this application. I see that you're located off Peachtree Industrial in Norcross. Having lived in Atlanta and Duluth for 30+ years until I moved to Nashville, I feel that people get beat over the head constantly with peachtree this and that, so much so that it's cliche now.
It's the same with Nashville companies using the image of a guitar, cowboy boots, and the words "Music City" in their logos and literature. Its sooooo overdone.
I'd step back and understand what you want to communicate to customers when they enter the shop. Right now, its just a logo and a peach tree. It doesn't give them any useful information to help them understand what the company does, believes or strives for. Maybe a concise mission statement. Maybe a short testimonial. Start with what you want the customer know in the end after seeing the banner.
