Thanks. I made a few modifications here and there, but most of the work was already done by the original artist. I'm responsible for the camo and markings, though, which are based on historical French tanks (particularly the Char-B series, but others as well). I also drew the side-skirts, which none of the original drawings had.
In terms of design, I think they've got touches of the M18 Hellcat, Centurion, and Comet tanks - probably my favorite vehicles of this era, all around. You can probably see that I deliberately invoked the Comet look with the sand-guard design of the Char-8A2, and then the Centurion-style skirts of the Char-8A4.
