The artist only did the front (don't be lazy!) but based on current VW styling language for the MKVII it appears to be accurate although very similar to the MKVII GTI. This is basically that same design, lowered slightly, with a lip on the front bumper and more aggressive sideskirts. VWBoost hopes Volkswagen tweaks the looks a bit more than that.
The MKVII Golf is a great design so no doubt the Golf R will be pleasing to the eyes. We are all sufficiently teased, bring the car on already VW.
