Oh, uhmm, uhh. Cool Not sure if you've tweaked the background (both my monitors at work have shitty contrast and light blaring onto them atm, so can't tell) but my original design had a faded oval light shadow style behind the main text from memory. This may screw up your whole vinyl concept if it's not rectified prior to printing.
Definitely happy for this to be used, but it was only an alteration of Autumn33's submitted image (might want to check with him too) and therefore the size was pretty small. If you want a better quality one to avoid pixelation issues give me a couple of hours tonight (and the required font) and I'll be able to get one out for you easily enough. I'd be quite happy having this stuck to my car, as it's quite a simple design which would fit in nicely. That being said, if we're going ahead with this there may be some epic/awesome/fantastic graphic designers out there who could take a crack at an entirely different and more complex design?
