Had fun bringing this to life in Gravity Sketch and rendering in Keyshot. Did a super loose sketch in GS to start, then started building surfaces quickly. I prefer to work this way rather than try and resolve all the forms in 2D first. You won’t know until you get in 3D anyway so stay super loose early.
*Disclaimer, I did this for fun, not as contract work for SIDI. I wear their current motorcycle boots and they work fine just look kinda fussy I wanted something cleaner and more iconic.
