You know how people say that you should look at your own painting in the mirror so you could know if it's good? Well, I tried to do that with OGF maps, like this:
This way, you won't recognize your own maps, so it will be easier to tell if it's good.
What do you all think about this?
Edit: the point is that if you can't look at your own maps objectively, a mirrored image could help you have a different perspective.
