I really like your work. You have a good skill for drawing, but you also clearly have messages within your work, and a reason for drawing whatever you're drawing, which I respect so much.
I would like to suggest that you play more with backgrounds. Some pieces, like "Horse Kisses," makes sense without one, but others, like the cow with the guts, would benefit from being placed in a scene, so the viewer has more visual information to take in while thinking about what you're saying with the piece.
Keep up with the sweet work. I look forward to seeing more.
