Thank you all for your comments ĄĄĄ
Iīll try to corrrect the head angle of the kneeling soldier, but itīs hard to find the right one...
About the tracks, no problem because will be much more grass and corn plants, so only a little part will be visible...
About the ground work, itīs just natural cork base and das pronto terracotta, with some peebles from a home decoration bottle.
Iīm making a prototipe of corn plant with raffia; Iīll send pictures of the results.
Much more work to do...
Best regards
Santiago
