Aww, you got rid of the path, I really loved that. Ok, so now it looks more serious and challengelike, but that was a seriously cool piece of pure-mana light. Would it be horrible of me to ask you to post that as a png by itself? I promise not to steal it, but it'd be a great thing to be able to overlay onto my concept sketches so I can visualize what the skies of my alternate-reality plane might look like.

And, probably more importantly, the map looks great. On the big cities, you have a height progression going as well as fire-size. Maybe a signal-fire-tower might look cool for the biggest points of light.
