Looks good. I have an electrolysis system and a lye tank, and have bought restored and sold hundreds of skillets of the last couple years. I usually do one light coat of seasoning on mine and then start using them. Like you said, using them is the best.
When I season mine to start I spray them with cooking spray. I wipe and wipe and wipe some more until it basically looks dry. Then I stick them in the oven on 350, after 10 minutes I remove them and wipe then down with the same paper towel I wiped them clean with. This ensures and even coat of oil. They stay at 350 for an hour then I turn it up to 400 1/2 hour, then to 450 1/2 then turn the stove off.
These old skillets are so versatile and cook so good. I use them on the stove, in the oven and over a camp fire.
