Kent is a super supporter of sculpt it first and then retop, instead of box modeling everything without a guide mesh. It’s a longer process, but I like that approach as well, because when you sculpt first, you get a freedom of just creating without worrying on topology and stuff. It’s harder when there’s nothing there to just box model away. But when you have sculpted a base mesh first, you have something there and then it’s easier to visualize the edge flow.
