I like where this one is going! Some extra polish would go a long way, such as using Lerps, and squash and squish animations to show when things happen. I also wasn't sure about when my guys had attacks available or not.
I would love to see an option to turn on auto-time, where both sides are controlled by the AI until you pause the game again. (sorry, probably way more scope than you want)
I saw below that there is a lot going on behind the scenes instead of just a single attack. If there are attack rolls and such you must make it obvious to the player! it was totally invisible to me. Find someone's dice rolling animation or something, and get some floating combat text for misses hits and crits.
maybe add a window when you click on a unit (when building your army) that shows their stats
