A Porsche 911 CTR2 Yellowbird rendered in golden, buttery, creamy mashed potatoes with some lumps and scraps of skin garnished with a couple of sprigs of green herbs. every detail picked out in the mash as a replacement texture for the original material resulting in the most wonderfully tasty looking, toasted at the peaks  of heaped mashed potats assembled so as to recreate a perfectly recognisable Porsche but in this new mashed potato medium. there should be warm,  quite strongly diffused but intense lighting not visible to the viewer, i.e. off camera to provide a source of enhancement to make the mashed potato Porsche appear as best illuminated as possible. this mashed potato Porsche must look like the most appetising mash ever imaginable yet still a speedy Porsche!  you must keep strictly to the Porsche shape and dimensions, especially relative dimensions. likewise the available Porsche colours must not be strayed from, recognisability is key. any features visibly recognisable are also essential. always the mash Porsche must be visibly recreated from mashed potatoes. where possible keep parts of the Porsche that are of relatively uniform texture composed of uniform size and shape mash granularity.
