It's a shame you never managed to realise some of the ideas you had in your concept art post. The art looks absolutely fantastic, and the death animations you've made are heckin' great. With the characters being so tiny on screen you lose absolutely all of that detail. Could the characters not have just been bigger? Or was this done as a way to increase the distance between them?
If that was the reason, I wonder if you could have done some kind split screen Advance Wars type view.
Great effort though! Lovely work.
