Lumpy Cams

C'est ce qu'une entreprise en/au(x) Australia recherchait pour leur t-shirt design

Please see photo of my idea attached. This is exactly what I want, but I need your expertise to improve it :) I want it to remain a black/grey sketch design, as it's to be printed on white shirts. Target audience will be motor enthusiasts so I don't want anything that looks like graffiti art. Think mechanical / industrial. I would like the camshaft along the bottom to remain a drawing but the cams themselves could be thicker and all match in size. They are supposed to be comically larger than real cams. This design will be the logo for our clothing company and it will also be printed on the shirts.

I have found a font in Openoffice that I think will look good, called Chalkduster. I have uploaded a photo of it. This should match the sketch/drawing idea. Voir plus
