Nice work on the painting Igor. You are right though, it doesn't look right in the tones! Wojtek is spot on for the paint numbers, Humbrol 29 is definitely the Dark Earth, where the one used looks more like the wine red/brown used in German vehicle camoflage. The Humbrol colour I recently bought for Mid Stone, and listed as such on the paint rack at the shop, was Humbrol 225. But as Wojtek pointed out, in smaller scale, all colours need to be made just a touch lighter. It should be easy enough to repaint though, and the original paint could well provide a nice weathering effect underneath.
