@finticemo Thanks for your experiments! I think the main thing it demonstrated to me is that the perspective on the cleaner version is probably a little off, which shows in your straightened up version. I did also like to see what the filters did though.
But I want to note that I don’t currently see a need to change the Tiled logo. It has looked roughly this way since I originally drew it back in 2004 for the Java-based version of Tiled:
Of course, if we get to a “Tiled 2” kind of thing it may be time for something new, but I think the current one will do fine for Tiled 1.x.
