If you just want to make A bow so you can say you did it or so you have a bow to shoot then, yes, do a build along and get a bow made that will last. If you want to build more bows in the future, and get better, then I would use this bow to do some more learning by exhausting all possible changes to it. Then, start another bow and try to make that perfect bow. If it comes close to what you wanted then call it good and start another. If it doesn't, use it to do some more learning and start again.
That way you are actually making many bows from just a couple of boards.
So I would either get the handle bending on that bow or back the bow or recurve it or whatever.
