This is the collaboration I came up with in the end. Absolutely stoked as to how this sketch turned out. My main focus was to depict the detail of the machine, but had to have the lads in the collaboration.
The badges and their markings are manufacturing stamps, of where the gun/part of gun was made, what regiment the gun will/was to be used and what year it was made...E.g. Production and manufacturers.
A3 paper - Pencils H, 5HB, 6B, & ‘Mont Marte’ paper stump for rendering.
