What's wrong? The picture is beautiful, I like it. And in general, the concept is interesting, if you ignore all sorts of "Vasya." But I wonder how to implement this in the game, since the development of WoG 3.59 and HotA has long been stalled? Or are there any possibilities?

I've seen this somewhere :) Well, I think it needs a little work, to be adapted to the Heroes style. For example, in some graphics editors, you can add a picture effect.
