You've cracked the camo pattern on the Denison smock perfectly, Steve - sweeping the brush across the base colour is exactly how the original was done, & the colours you've chosen are pretty close to the prototypes, to my eye.
Blanco colour for the webbing looks close to the original too, & the mid pouch on the rear of the figure's belt is the haversack for the 1942-Pattern Light Respirator, which remained in service until the late 1960s.
Keep at it, you're doing a great job here!
