How can I make my head appear larger, and how can I make my face appear more even? (photos)

I have a smaller sized head about 21.5" in circumference. I'm 5'7 with a thin upper body, and muscular lower body. I'm really insecure about how small and weird my head looks. I have a bigger forehead, and all of my features seem lopsided. Is there any surgery(/surgeries) that would even out my features and make my head appear bigger? My profile is flat and I have a triangular looking nose. I feel as though I look like a bad cartoon character. Please let me know $$ estimate if you can as well.
