This guy was a bit of a pickle for me. And I really need to give co-design credit the Justin Thomas, the Art Director at Luxoflux for this one. These were the sketches I turned in for review, based on a Bearcat armored car...now I usually don't mention my faves when I turn in these sketches, but I remember it being clear to me that the middle one might have worked best.
But they picked the one that was dotted, and when I turned in this drawing for a pre-final check before submisssion, I got this image reworked into a rough version you can see below. JT did some photoshop magic to squash and stretch elements into this basic shape*, and I redrew it for final.
Normally I am pretty open to making changes, but this time it was a little annoying to have basically this version already in the thumbnails (drop the ribcage armor, and it's pretty close, I thought) and to go to final drawing with another. Time was tight for this, and I had a bunch of these robot grayscales to submit for Hasbro review...though overall, I think it was a great choice to go this way instead.
*I couldn't find the reworked feedback version...stuff like that got saved to a feedback folder, which I don't archive afte projects, so it's lost (to me anyways) forever.
