How to pinch a hole into a UV Sphere?

Question

I'm a Blender beginner and I'm trying to create a pumpkin creature for my game.

The problem is that I am using a UV Sphere to create the pumpkin and using a Boolean Modifier to make the eye and nose holes in my pumpkin, but the mesh is looking somewhat strange.

I'm using a Subdivision Modifier to try to solve this problem, but it still looks strange.

I tried to make a new topology for this area, using a Plane with Subdivision and Shrinkwrap modifiers. It looks better, but still strange:

• Press I to Inset faces and move mouse inwards
• Press X → Delete Faces
• Press Ctrl+R to add Loop Cuts and scroll mouse forward. Click LMB or press Enter.
• Select Edge Loop of the hole with Alt+LMB and press F to fill a face
• Enable Proportional Editing and select Sphere as Falloff
• Set Transform Orientation to Normal
• Select the center face and press Ctrl+Numpad+ to increase the selection
• Press Ctrl+I to invert selection and press H to hide faces
• Select center face and press GZ and move mouse to push face inwards along face Normal.
• Use mouse scroll wheel to adjust the size of the proportional editing influence
