I have come across several furry artists who has a lot of chaos in their artwork. However, you can zoom in anywhere on the image and there are so many details and easter eggs to be found. AI is not going to hide a pokemon in the background.

Being a full nerd this weekend and attending Power Morphicon. You heard that right, a full weekend of Power Rangers. Been a fun weekend so far, met a friend’s sister who is a ranger, and ran a ranger 5k. Sometimes it’s fun to just do the thing and try.
