Howdy PB,
I think you've done a dandy job of it mate! The overall finish (colour) is great. But I'd scuff it up a bit, around some of the obvious places, plus the headlight guards, tow cable ends, drive sprocket teeth, etc. And since I believe (let's see what Hollowpoint says

) the most common route into the tank was right up the front across the trans cover and glacis plate, unless your crew has WW II era anti-gravity boots I'd think about some 'wear& tear' along that route (looking for obvious foot/hand holds).
I also noticed the (bow) MG right off. But that shouldn't be too hard to correct.
Oh, and 'thebear' makes some very good points. I see a lot of stowage portrayed with the tie-down rope looking more like
lay-over rope!

Since the rope is usually cinched nice and tight, as thebear said, it should 'dig' into soft stowage, and be almost drum tight across 'open' spce between bundles. Colour diversity is also important. Subtle mixes of colour difference between bed rolls, knapsacks, etc is a very good point. Same goes for the Gerry cans. The only time I've ever seen Gerry cans the exact same colour was in a parade. Most times they're almost completely different colours to easily identify what it contains at a glance.
Oh, and that rear .50 cal British MG mount .................nah, won't touch that!

Just kidding PB......really nice job. I really like your hand-applied decals, and art work!
Tread.
