Would you mind sharing what colours you used?
Of the top of my head
I used a mixture of mp miniature paints bottle green, with a bottle green/olive green mix for highlights for the green sections
vallejo english uniform for the base followed by a mp paints khaki along with a very watered down black paint wash over it all.
red-brown was tamiya and I added a little burgundy to it for highlights
stripes where vallejo beige and the gun barrel was english uniform and leather brown mix and gun metal was gunze black steel.
The order I did it in was english uniform base, tracks, green base, gun barrel, khaki, red-brown, highlights, black wash and stripes
I may have used some other paints but I really cannot remember exactly waht they where, Hopefully this helps.
