I really like what your doing here. I would like to see some variations with brighter colors and less gradients, as they dont print well on shirts and cannot be used on emroidered hats. Maybe also try a version without the box and a little more definition on the truck and trailer. Since the background is black with the box, without the box the grass would be white cutting out parts of the word "GRASS", that might actually look cool. Good job so far.
