Very nice Firefly - you should be proud. Congrats.
As you've built such a nice model, I hate to come over all pedantic and act like a button counter - you've built a lovely 1DP Firefly BUT your crew figure appears to have a British-style cap badge. His beret should have a Polish Army Eagle (clutching an Amazonian shield). Equally, you could have included his rank on his epaulettes - stars if he's an Officer, red and silver braiding if he's a Senior NCO. Although not always the case with frontline troops, he could also have the POLAND shoulder patches - white lettering on red arched background. If you go the whole hog with the insignia, he could also have the regimental collar pennons. Finally, as your crew figure represents the vehicle commander you might think about fitting him out with headphones and mike. Please email me if you want further info on any of the above - I can send you scans of the relevent info.
Like I said at the start, I don't want to come over like some know-it-all idiot. You've produced a lovely model, which you should be very pleased with. I hope my comments on the fig are useful.
All the best and keep it coming.
Cheers
Karol
