Looks good. You can also fill the pan with straight vinegar it dissolves the rust in short order. I soak the pans on lye water for a few days and it loosens all of the previous cooked on coatings . When you take them out and rinse and dry they immediately get a coat of rust. I then hit them with vinegar, dry and season. I have a complete set of Griswold skillets and Dutch ovens pre 1920 that I picked up at garage sales over the years.
