Will resectioning the corrugator muscle give me an unnatural appearance? (Photo)

It's very important to only perform a partial resection/ weakening of the muscle so that there's still movement and retain some scowling ability. If the muscle is very strong like in the photographs, it will continue to give you dermal, atrophy wrinkles between your eyebrows, and pull your eyebrows more downward every time you contract the muscle.

It may be very helpful, if you did not try it before, to have Botox delivered for the purpose of paralysis of corrugator muscle to see what result you may expect with corrugator resection. As mentioned recently in my comment, it is never a complete resection. The same principle may be applied for brow lift leaving the lateral portion of frontalis muscle intact, untreated. Hope this helps. Good luck.

Corrugator release is a fairly routine part of browlift surgery and can look very aesthetically pleasing. Based on your photo, it should be a part of the browlift surgical plan for you. Over-elevation of the central brow tends to give an individual a strange look and should be avoided. I recommend looking at your operating Surgeon's results and making a decision about whether you like the appearance or not.
