Crasken Farm logo

I was commisioned by an eco farm to design then a logo which shows what their all about. This will be printed on the uniform, T-shirts (to sell) Dinning sets (it holds events such as weddings and private parties etc) and all manner of advertising.
They wanted something which went with the theme of nature and the 4 sessions depicted through the shape of a key hole...and they also wanted the green man in there some how. this was all to be desinged in a celtic/tribal design

After a few attempts i came up with this design which they chose.
Can you see the hidden green man, 4 sessions etc? =]
