Oooohhhh… while it would probably be infeasible, custom art of the troops would be sweet af! Maybe some of the more artistic types on this forum could submit fanart, and the devs can pick one? That would be really cool! 
From those who voted it seems these are the most popular picks so far:
Alastair
Celestasia
Goblin Rocket
Hydra
Salamander
Shadow Dragon
I think Shadow Dragon and Celestasia at the same time would be pretty sweet. Move the loading bar bottom-center, swap the background out to something more neutral or dynamic. Get the whole good versus evil thing going on!

I vote no T&A, the current iPad full screen can lead people to completely misjudge my choice in games…
Only one to choose, Rockworm.
You are so reliable, @eika
