How can I improve my state machine code?

[Konjointed]

I made a pretty simple state class that does what it’s supposed to do (handles changing the players state), however, I feel like it can be improved I’m just not entirely sure how since I don’t have too much experience with state machines.

function State.new(fighter)
	local self = setmetatable({},State)
	
	self.input = fighter.input
	self.states = FSM.create({
		initial = "Neutral",
		events = {
			{name = "Neutral",  from = "*",  to = "Neutral"},
			{name = "Crouch",  from = "Neutral",  to = "Crouch"},
			{name = "Jump",  from = "Neutral",  to = "Jump"},
			{name = "Land", from = "Jump", to = "Neutral"},
			{name = "Hit",  from = "*",  to = "Hit"},
			{name = "Special",  from = "*",  to = "Special"},
			{name = "Throw",  from = "Neutral",  to = "Throw"},
			{name = "Recovery",  from = "Hit",  to = "Recovery"},
			{name = "Knockdown",  from = "*",  to = "Knockdown"},
			{name = "Taunt",  from = "Neutral",  to = "Taunt"},
		},	
	})
	
	Movement.onLanded:Connect(function()
		self.states:Land()
	end)
	
	RunService:BindToRenderStep("State",Enum.RenderPriority.Character.Value,function()
		self:update()
	end)	
	
	return self
end

function State:update()
	local currentState = self.states.current

	if self.input:isKeyDown(self.input.keybinds.Down) and currentState ~= "Crouch" then
		self.states:Crouch()
	end

	if self.input:isKeyDown(self.input.keybinds.Up) and currentState ~= "Jump" then
		self.states:Jump()
	end
		
	if not self.input:isKeyDown(self.input.keybinds.Down) and not self.input:isKeyDown(self.input.keybinds.Up) and 
		currentState ~= "Neutral" and currentState ~= "Jump"  then
		self.states:Neutral()
	end
end
