Thanks everyone for your kind comments!
I've had some crazy weeks at work and I couldn't find a minute to post my advances, but finally here they are:
I finished painting the roof canvas with some desert camo:
I had the image in my head of a humvee ramming a door (still don't remember if I saw that in Generation Kill, Call of Duty or the news...) Anyway, I thought it was a powerful image so I just tried something like that:
First I painted and weathered one of the rubber tires of the kit:
Then I cut a pewter sheet to get a sling:
Next, I placed the tire in the grid:
Some adjustments and a photoetched hook:
And there you have, a menacing ram!
Afterwards I airbrushed some green and brown, just like if the owners would haved use some spray cans, as you can see in some pictures:
Step by step, it's nearly to be finished...
Regards!
