Yeah, I'm afraid for my money (which it would be), the proportions and basic sculpting aren't quite there.
The shape and size of the helmets look odd (the dome too high and the rim too small).
The rifles look too long and chunky, whilst the Bren looks too slim and the barrel is poorly sculpted.
The head and necks look oddly positioned, too upright and far back, like they're on parade or have just been startled by finding something odd in their teacup.
Overall, they remind me of the old Esci 1:72 plastic soldiers.
I applaud the dedication and work put in though and hopefully the sculptor will just go from strength to strength and future work will be far superior I'm sure.
