Looks good enough to me though on the battlefield considering the ebb & flow of it I just keep it simple. Try to take advantage of the first 3 rows & avoid the last row if possible.
You can get silly complex & rate each terrain for its protection & detection properties, effectiveness vs artillery etc but you would spend ages figuring out what is the absolute optimum for that situation & what you need to achieve. Wisp of smoke there now improves those hexes detection rate etc etc.
