Natural Process Logo Designs

We had a new fun comp to enter on the graphic and web design forum is was a logo for a company called natural process. I came up with three alternatives here...







Although I dived in to the logo designs very fast I think the first design is maybe my favourite. I'm not sure about the orange colour, I tried it in green but the orange seemed more earthy.
There's been quite a few entries to this logo competition and a few decent logos.

I'm going to upload them to my logosauce profile and see if they gain any points.
