Nice work Zappa, the bren carrier is definitely a cool vehicle and you've done it justice, love the dustiness of it!
If you do decide to paint figures again might I suggest you start with some better quality figures, Tamiya vehicles are good but the figures lack detail.
Probably start with some from Dragon, especially the Gen 2 figures, Miniart or Masterbox which are all fairly inexpensive and you'll be surprised how much better they are and what a better result you get!
Look forward to seeing more from you
