Wow looks great. The cinematic feature i think is both good for fast battles etc and bad being slightly unrealistic or showing possible traps the player may want to keep hidden. Although can you possibly put in a feature to remove it at the players choice. That way you can have the possibility of going in blind like a true siege.
With regard to the leveling up. Will you be able to make changes in game to them imediatly as they level up or does it just affect health and strength etc?
With the leveling up does it also change the units health to full? As some games have when a unit levels up?
I know alot of questions but really looks a good job

NIce one to all involved
Oo also will this be purly PVP or PVE aswell?
