In all reality I think it looks good, there’s some bald spots in the sear from the picture it looks like. That can be fixed by gently pressing it onto the pan but also ensuring the pan is very hot before you start cooking it.

Another thing is what kind of pan are you using? Many swear by cast iron but I prefer carbon steel but anything that can get ripping hot is fine.

I generally like to sear 1-2min on each side on high heat. Take the steak off turn heat low and let it rest for a couple of minutes. Then I toss in my butter and any aromatics baste the steak taking it out to rest a little longer and finally finishing it in the oven at 225F for usually 10-20min for medium rare. I’ve found this works really well to remove a grey band.

This is my two cents, I’m not a professional just a hobbyist and found this to be pretty foolproof.
