Yeah, when I said to SNOT the rock, I meant make a rough wall with your gray bricks and slopes and turn it on its side. Some BURPs or LURPs turned on their side would work too. The river is good, but I don't think so much tan along the bank looks right in this scene -- a little brown would look better, or maybe just more greenery to cover the fact that the water is higher than the ground level! All assuming you have the pieces, of course, but that's my two cents for a v.3. Nice job fleshing it out with more fights in this one.
I don't have too many either [I max out mine on every vig]. A good battle scene, and I would spend that limited money on more bush/shrubs pieces, it would really help the scenery. And more gore...lots more
