I am also very happy with my new terrain, both how it is generated & how I have actualised it.

Using 10mm figures has its advantages in that I can use a smaller board for most games.
For RRtK it is 3'x3' & a defender can choose which of the 4 sides to deploy on. Of course, the attacker may refuse, trying to outflank you, but if he does so too many times, he will forfeit his attack & reduce his National Morale - not a good thing to do.

The basic 3'x3'

3D terrain pieces. They do not have to be pretty, just reasonably precise in their measurements.

The bare bones of a terrain selection with a Gulley in the left foreground & right background, a River running through it & a few hills, one quite high, giving 5 seperate levels (count 'em)

The same table, dressed with a Cigar Box Battlemat & with Woods, Impassable Rocky Ground & the actual blue River adorning the field, plus 2 or 3 fields for show, in this case.

The Brethren prepare to resist the onslaught of the Golden Horde as they sweep across the River.

Not too bad, huh?
