Missed this thread when it was started
(Probably during my usual "absent-from-SFM-for-months-at-a-time" which has become too frequent in the last few years)
Either way, having gone through the entire thread it was interesting to see the various stages on that cluster of pics on page 2.

Although at the bottom of page 1, the second image thumbnail, I was like: "
Wtf, suddenly he's doing a car of some sort" LOL
There's something about the positioning and style of the "headlights" that I really like. Can't tell what exactly, but I think it's tank related though.
