T-shirt logo for Oslo Motor Show

A little while ago, I was asked by the Oslo Motor Show to make a logo for this year´s show.. and this is what I came up with. The show is full of custom cars, motorcycles, trucks and most motorised stuff on land.. so the pistons, spark plug and tools should cover the most, and I used the font I was designing. Hope you like! :-) Any constructive criticism is always cool..
