Still posting old pieces before the newer ones... This was a different run of going monochrome to a certain extent with a marker I found roaming around Michael's at the time. Granted, shading is a bit basic and not very detailed, but I still like it.
This was mostly inspired by Sonic 3 and Knuckles' Icecap Zone. Although I can see some bits of inspiration from Icecap out of Sonic Adventure with the snowboard and a more modernized Sonic design.
