Okay- you could have it towing the tamiya 6 pounder. Resicast also do a resin version in towing mode. The figure camo is way off. I would go back and paint the figures Khaki- even the driver- if you can see it then with a little careful work you can paint it

A couple of oddx things about the carrier- why did you attach the large bag with the net to the side instead of the back. Also the packs- on a real carrier there is nothing there to attach them to.
While troops in the desert and in the early stages of the Italian Campaign attached gear to the sides of their vehicles, in NWE this wasn't common practice
