Postage Stamps//rough designs

So from the design sheets i have been doing for the idea of efficient driving, i drew up some rough ideas on illustrator, so i could see which was looking the strongest and best for the stamp design.

These are only rough designs, so they aren't perfect in the aesthetics of them, just to give some idea in the crit tomorrow really. I did come up with the name 'eco-drive' but then from looking on the internet that name is used a lot within car branding for 'eco-friendly' cars, so maybe ill have to have a re-think. 

Just chucking out ideas really!
