Finally, nearly a month after I actually finished work on the original version of this piece (as you see it here) and several months after starting talks with my client ~KerenskyLI
planning it out, I am able to post this at last. This piece took me quite outside my comfort zone as I still don't consider myself especially proficient with drawing/painting complicated inorganic objects (which I suppose a Russian KV-85 tank would certainly qualify as) but in the end I'm relatively happy with it, and am relieved to be able to post it at last.
In my own opinion, this picture is quite reminiscent of my Steampunk Rarity
artwork in many ways, but this is essentially exactly what my client asked for and he was happy with it, which is the most important thing of course! And I did have quite a lot of fun working on it, which is always a nice thing.
