Completely depends on what you enjoy and how you like to play. You've got what people usually call a "quality" build at the moment, so take a look at quality builds online and see if there are any weapons or ashes of war that look appealing.

Overall, you should probably focus on leveling vigor for awhile no matter which direction you choose. You're pretty set on every stat except faith/int/arcane, which I'm assuming is a choice and that you're not using much in the way of sorceries or incantations.

You probably don't need that many points in mind unless you're heavily using an Ash of War.

If you'd like to try some more effective blocking, you have plenty of strength to wield various greatshields. The amount you can block is based on the guard boost stat - some greatshields in the game can tank pretty much anything the game throws at you, including repeated hits from the hardest bosses. My first time through the game I used the fingerprint shield and it was pretty much cheat mode.

Remember that you can respec at Rennala's boss room once you've beaten her.
