I think you should perhaps steer away from the geometric letterforms and box, and move to something a little more organic. Not a trendy hand drawn logo, but maybe something alittle softer, more natural. The logo as it stands looks a little like a christmas present.
I like the combo of greens, but not the square boundary. I think you would have more success to simply choose a nice serif font for the letters and use a circle to confine the forms. Simple and elegant.
Thanks for the comments Jim, sorry slow to reply havent been on the forum for a while. I really wanted to try and stay away from the organic, dont know why but wanted to try and break the norm, seen too many organic ones lately perhaps.
