Hi Francisco,
Excellent work mate.Superbly detailing a tank and groundwork in 1/72 scale is by no means an easy feat..hats off to you!
I do agree with Claude though, i would of liked to of seen it on a bigger base.
Secondly, this is my own personal opinion but i think the black plastic base does not compliment the dio very well.A wooden base would of been much more appropriate and had given a somewhat extra "vintage" look.
It's great to see someone else depicting a W.W.1 diorama, modelers seem to forget there was a First World War before the second one ever came about

!
Cheers,
Shay
