Eric, I agree with the comments, your Semovente is looking good, definetly got the bolts popping. Considering the desert environment, another option would of been to have dust/sand accumulated around them and then drybrush the surfaces of the bolt heads to an exposed dark metal colour.

After exchanging a few messages with Rob (Panzerwaffe) on how to best attach the small vehicle to a base, I decided to tempt the hands of fate and use brass pins. Due to the small frailty of the model, he suggested forgoing the pin method and just apply glue to the bottom of the tracks. Hind site now says I should of done just that.
At first I had just four pins in, located centrally on the more sturdier wheels. I realized though the extreme ends would be more important anchor points to keep the tracks in proper contact with the ground - so added four more pins (this is what happens when one doesn't plan ahead - d'oh!). Too many pins now so snipped the initial four. Drill bit was 0.4mm and the brass 0.3mm size.
I had major problems getting the pins to insert into the holes in the base, but after some test fitting everything seemed a go and was ready to apply the adhesive (white glue along the track length, and super glue gel on the pins). I ended up snipping both pins on one side as they just wouldn't go in, and actually buckled under the pressure I was applying.
Finally got it settled down and applied one final bit of pressure, and that's when I heard a faint snap and some plastic bits hitting the floor. One of the tracks came undone, and all four covers for the duel wheel sets had come off - a result of using resin and regular plastic parts. Surprisingly, neither of the crew hatches broke, something I've been doing quite regularly with this build.
Should be an easy fix. I am concerned about the second road wheel from the front. Looks a bit wonky and up in the air. I didn't notice until the first photo posted above, but this was a problem area already before attachment to the base.
