Chris,
My first look on the map:
1. Overall feeling: Very nice map sample
2. Too much use of cultivated fields on this region (not presence of irrigation works, farmer huts, plain/leveled ground).
3. Not any presence of tall grass (especially near the banks of the river/stream)
4. The bombarded hexes are mainly rough hexes(?)
5. The morphology of the ground is not leveled for this kind of terrain. Usually this kind of ground (not rough/rocky) follows a more smooth variation of heights.
6. Nice use of earth ground in the clear near the stream (maybe you could add some mud?)
7. Nice use of terrain for tactics (cover, visibility etc... in the shell holes)
good work Chris!
p.s I think the green areas are a mix of short grass and high grass; the areas protected from the wind should have tall grass and the areas exposed to the wind should have short grass. We should find more photos of the area; I will try to find some
