Right... after taking in some suggestions I've made some modifications and added to the map. Still not done. I added some earthworks in the lower right, but I'm not convinced I need them given that they're not anywhere else on the map. Also, the trees that line the fields are intended to be more hedgerows. I may separate them off onto a different sheet and lower their shadows to make it distinctive that those pieces are short hedges and don't block line of sight as much. Anyway, here's a smaller picture of how it looks:



And if you want to get in really close:

I've also added a spring-fed creek to emphasize the ravine in the lower part of the map. Hopefully that will direct the overall expectations of the battle to the southeast part of the map. Of course, I'll still have some skirmishers try to flank, but assuming the heroes secure an alliance with some elves, they'll be holding down that part of the flank with little difficulty
