Well I'm calling phase two done (for now anyway ). The first pic is of the whole layout pretty much. The second pic is an overall of phase two and the third is of the right side looking toward the main layout.
I think you could do N-scale cow flops by dipping the tip of a fine brush in artist's acrylic and touching it down here & there in your field. I think some texture would be visible on close inspection. If I have time tonight, I'll try this in HO and post a picture. I suppose the color varies with what the cows eat, but in New England Raw Umber is a good starting point.
Mike, I'm just catching up on your thread. Very, very impressive and inspiring! That overall shot is excellent. You blended the scenery into the backdrop extremely well. The colors and proportion are perfect. And your detailing is excellent. Well done!
