I like this. Can you try it some different bolder colors. Black and Red or Black and Blue. Maybe lose the wheat and try to make C and A and T a little more definitive. I like the C A & T logo idea. I just want it bolder and more certain of itself.
Keep playing with that if you have time. Maybe even thicker on the C, a little thicker on the A and the same on the T. Just to separate the letters a little.
