"I absolutely adore BTTF, and the second one is everyone's favourite isn't it! I was really stoked to get Griff - he's such a jerk but he's a brilliant character. Straight away I thought of his Pitbull hoverboard and his extending baseball bat he has. I wanted to keep the graphic strong and simple, so went for a graphic design-style approach to the crossed bats, and then made his overboard silhouette circular so it sat nicely behind the face of Griff!"
