@dragonice69 The fact you attempted this with a mouse is very, very brave. You pulled it off pretty well too, so good work!
To echo some comments being thrown around here, making the eyes a separate mesh is much better than carving them into the sculpt in my opinion. I usually use the crease brush, set it to subtract, enable smooth stroke and “draw” an outline for my eye, then use the inflation brush (set to deflate) to hollow out the sockets. You can then use other brushes like pinch and crease to tighten it up.
