I finished this little kit last weekend, it is Airfix’s 1/76 Mk IV Male tank. It was a quick build, being all put together in one evening, then painted, washed and weathered over the weekend. The “mud” was my first attempt at the stuff and is a blend of flour, white glue, cocoa and a drop of earth red paint. Very enjoyable break from the clutter of projects still in the works.
Pretty fair effort! I see that you’ve modelled one of the later vehicles, without the steering wheels.
One small point, however. The Airfix 1/76 British WWI tank is a Mk.I male, not a MK.IV male. An important visible difference between the two tanks was that the Mk.IV carried four Hotchkiss MGs as well as the two 6pdrs guns of the Mk.I male, and the 6pdrs’ barrels were now shorter. The conversion is fairly simple, or you could just buy the Emhar 1/72 Mk.IV male:

Also, it helps if you add weight to the rear of the vehicle, to give it a more realistic sit. On the real thing, the heavy bits (the engines, mostly) were towards the rear.
Cheers,
Chris.
