Someone should create the artwork; they would be top-tier creatures. If you start working on the image now, it will take 100 years, and so on, and then you might get the same glitches after all that work because Heroes 7 is much more demanding on the player's computer than what we have now. Well, you could take images directly from the game, and it would even be better, but who would create the animations?
If I could, I would do it myself.
