Here is a very simple cornfield.
Consists of three different corn plants.
Texture is included, but not suitable for close up shots, I think.
This is great, Bob - it reminds me of the maize mazes at Tully's Farm in Sussex (South East UK) not far from where I live. Every year they have a different design, open to visitors to walk around, with bridges and other things. It's fun to go round in a party. I think they wait until the maize is grown and then carve the design: pirate ship, dragon, owl, etc.
Then they [photograph it from the air] (https://www.google.co.uk/search?q=tulleys+farm+maze&lr=lang_en&hl=en&as_qdr=all&tbs=lr:lang_1en&tbm=isch&tbo=u&source=univ&sa=X&ei=EkEZVLLTFIHC7AbRmYGwAw&ved=0CEwQsAQ). I thought it might inspire you further :-)
Good and cool! :D Thanks
