Yammer Hackday 2015 t-shirt

A t-shirt design from 2015 for the Hackday at Yammer… yes, you guessed it right! It was all about Back to the future theme.

Attaching a couple of rough previews, the illustration was placed on the chest area.

I didn't want to put another hoverboard so I found the boot pretty interesting, it's based in some ideas from @Ryan Putnam (thanks for your inspiration, man!).
