Looks pretty good. Similar to the Katrina campaign. But you've only posted the maps; you still need to group them into campaigns. In the first map, the description says you need to kill the deputy, but the victory condition is to find an artifact. So, I'd like a clearer description. In the fifth map, the goal is to capture a castle, but the description says to kill a hero. But that's a minor issue. You could think about balancing it, making it more challenging, but adding useful events.
My advice is to review the Katrina campaign and take note of what's useful.
But overall, it's quite good.

Don't rush to post everything at once. Do it in parts, focusing on filling in details, balancing, and other aspects.
