I like your scene very much. As i can understand the rest of the half track crew is six feet under!!!! and the one talking on the phone with his girlfriend is about to meet them soon. nice thinking, nice setup, nice worked out. As u say some more weathering on the half track , will show it even better , (the seats and everything that seems fresh painted must seem worned out and used) maybe some battle damage on the half track also . ,bended fender, bullet holes and all these.
There is a case id be wondering, since the half track was trapped and 3out of 4 are dead , if the last one would have the courage and will to bury the rest ...but thats a different item. The guys uniform behind the half track looks alil shiny but maybe thats the picture of it. some pastel treatment will make it nicely showing. Take care not to go hard on blood trails, cause they might look fake. Dot try to make them very visible, better understated than pickin eye!!!!. The ground work is nice , gives the country feeling very nicely and i like it so far. I d give some more detailing on the crosses of the buried to prove how the two crossed woods are joined. Nails? rope? something cause they didnt have glue!!!!
Its a very very nice scene, and being your first i d say that u have a bright dio modelling future in front of you. Fresh ideas(that u have !!) and patience is the trick.
Keep like that and i ll be happy to assist u on anything u might need .
