From what I can make out It consists of a central circle with many smaller circles of differing sizes arranged around the outside of the main one. It is not very large, possibly 150 ft max.

Unfortunately this crop circle bares all the hallmarks of being a man made hoax. Specifically the top layer of this crop circle is completely covered in mud. I do not mean a few muddy paths left around the circle by the apparently few visitors so far in the day, but systematically covered in a thin layer of mud over every part of the circle. I have attached many pictures to show the extent of this 'fouling from above'. Other notable features include the fact that most of the circles are heavily pressed to the floor and very muddy in the centres and although remaining muddy to the outside they are far less trodden here. There are some nice swirls and weavings but given the evidence on the ground I would have to conclude that this crop circle is most definitely a rather poor man made attempt. I conclude this mostly due to the systematic deposit of large amounts of mud on the entire upper surface of the crop circle, this is consistent with being trodden flat with muddy boots and a board. It should be noted that it rained heavily the day before and into the evening of the night on which this circle appeared leaving the ground wet and muddy. By the time of our visit the next morning the ground was still slightly damp yet we left no muddy marks on the circle as we walked around it. Other factors that lead me to believe this to be mechanically made by man are the relatively simple geometry and the small size when compared to other formations in the area over the past weeks and also the fact that a set of tramlines runs conveniently through the dead centre point of the formation.
 

All in all very poor and not difficult to spot as a hoax on the ground. It is however interesting to note that some moderately good swirls and sculptures are not out of the reach of man and his plank.....
