You have a real lot of patience, something that not many young fellas have.
That is a great job and you are doing it right by using mild to get the skills before trying harder and more expensive carbon steel.
I would give it another go and aim at the balance point in the correct position and just a better finish, then repeat again and again. Each time you will get better. Then move up to tool steel and heat treat the beast, not a job to take lightly.
Then the hilt has to be set up and a sheath, all skills to be learned in their own right.
All this advice is given by a simple tool maker, I do nothing like making swords, a few small knives for the kids but that is all.
Great first step!!
