These designs are done in illustrator and are what we call vectored. This means that the design is a series of vectors or angles and this means you can down or upscale the image to any size and there will be zero loss of quality. Essentially this is a design that can be used for tiny thumbnails all the way up to huge billboards. We do this so that you aren't limited once you purchase it. :)
just thought i would let you know i am happy to email you the black/white alternative after the contest ends should you choose mine (for free of course)
