Thank you very much! Haha, this was actually a second iteration, and I did have a person on the first: [link] The two are next to each other in my sketchbook, so I somehow didn't bother with the person on the second. Now that you mention it though, I probably should've just made them one deviation for clarity.
I was actually doing that for a IDW challenge on conceptart, topic "Anti-Orbit Self Propelled Artillery". But yeah, otherwise it would definitely need a cockpit
not to be picky or anything but manybe you could sraw a person 'to scale' ti give a better idea of size?
Awesome work.
