Another note of congratulations! That must have been quite the challenge, and I commend you for it. FWIW like @Roy Al I also think you look better with wider collars as opposed to the relatively compact BD you're wearing in the photo you provide. I have what I think is a fairly similar face (narrow-ish and tall) and I wear cutaways/spreads or large BDs, like Mercer's. And if you do like OCBDs or button down collars on dress shirts, I highly recommend Mercer.
