Is the hairline too conservative? (Photos)

I had a consultation for an FUE hair transplant a couple days ago with a surgeon I like but anticipated the projected hairline to be lower. He wants the hairline to look as natural and insists on using current hairline as a guide. Will the marked line take me back to my pictured (younger self) hairline? I specifically asked if my temples could be filled out more and he said it wouldn’t look natural. Just want to get more opinions before committing.
