Pretty good. Straightforward. I would suggest adding the following styles:
Skirmisher: Any feat based on Dodge
Dicer: (Put below Slicer) Any feat based on Two-Weapon Fighting
Marshal: Any feat based on Combat Focus.
The picture is perfect, and the class feature is easy to understand and works well. You even get good Reflex saves.
Are Weapon and Armor Proficiencies same as standard fighter?
