Wow guys, thanks!
I didn't think they were that good. I guess staring at it for so long makes me focus on what I messed up.
I'm a little bummed the weathering didn't turn out as I hoped on the CR gon. You can see on the proto CR gon, there's rust under the top lip at the top of the side ribs. It turned out too subtle. I think I need some new shades of rust paints.
