I've updated the oval to include the cow from #12 and added some grass in the mouth coming out in front of the banner with WAGYU. I also freshened up the color for a bit more punch. Let me know what you think.
I've incorporated your feedback into this design, switching the background to all sky, making the 'pasture prime' a bit larger, and enlarging the grass in the mouth to stand out a bit more, as well as lightening the color of the grass slightly
