Good to see you replaced those hideous old Tamiya gerry cans. Nice assortment of new and old cans and some German ones as well. Nice touch with the .30 cal. That said, the chipping is not consistent with the cleanliness of the seats. There appears to be a lot of paint damaged on teh cans and body but almost none on the rims. The tires also look very clean compared to the body work.
Is the Bren gun on a pintle? If so, the field is compromised by the gerry cans nest to it. I'd also go with a darker stock on and handle on the Bren. Vallejo makes a translucent natural wood you could apply over the color you have for a very realistic wood grain. It's a little thick so the brush strokes replicate wood grain nicely.
