Questions about modeling Sonic

Hello. I’m attempting to model something similar to the live action sonic model in blender. The current problem is the eyes. They have a lattice deformer, and I’m having a hard time with the oval pupil/cornea. I’ve tried boolean, and it looks weird. I want to approach this problem as it would in a real movie production. Any help is appreciated. Thank you in advance. Jesus loves you!!!sonic_render_1
