Bunny Head Cookie Cutter

I'm taking an online cookie decorating class, and instead of buying my cookie cutters, I decided to make my own. These are the first cookie cutters I've ever designed, so any feedback is appreciated. I designed it so that the end of the cutter is a bit thinner to sort of make a “blade” to cut through the dough. Cutter part will cut cookies approximately 7 cm wide x 10 cm tall (2.75" x 3.75")
