The Corn field looks great. As a farmer..... Corn is & has always varied in height, from 3’ on a dry year in sand to over 12’ for “forage corn” in moist or irrigated regions. In the upper-midwest, avg. field corn is 8 to 10’ tall. due to crop competition, corn generally grows to an even height, “if nutrients & soil moisture” permit.
I must say, also being a “farm toy” goy, this is one of the best looking “corn fields” I’ve ever seen on a layout, better than most “farm” layouts have. Marty
