My client sells batteries. In Australia we are coming up to winter. The cold weather can make a week battery fail. It does not snow where we are, but it can get very cold in the mornings. The client has asked for a side view of a snow man type character and a black & red generic car (Toyota Camry or 4wd suv).
I can bleed the back of the car off the tall DL flyer. (so it can be half a car)
I think the character can be a bit more 'develish' in nature, or like Mr Freeze from Batman or sort of like wicked Jack Frost.
Mainly it is a very simple illustration bordering on a cartoon. it can have a black outline or be solid colours (anime) It can just use 2 colours, black and/or red car to keep with the style - but it will be print full colour process. So you use a broad colour range, but it still needs to be a simple graphic that kicks a punch. I understand you'll use lots of cyan and light blue to simulate ice.
Headline will be Get a free battery check before the winter chill hits.
I think the bonnet needs to be up, ice may have settled on the top of the car and bonnet overnight and the character may be zapping the battery or somehow draining it power like a hungry alien or something to get the point across, that you old battery isn't going to start this car on this cold morning.
In summary, it's a vector based illustration, the bonnet of the car up and the 'snowman' is appearing to be zapping the battery. I think it's taking out all the charge (or maybe killing the battery)
I have included a sketch as a guide only
