Anyone know the artists name? I have seen a few others of theirs that I like.

It’s “Mr. Joshua”, aka Pants (or Pantspants). I have no idea why he never signs or watermarks his comics.

you don’t need to sign when you have your own style

It used to be very hard to find an artist even if they have a distinct style, but your search terms are ‘Spanish artist with a lot of unsettling characters hiding the pain and smiling’ or something like that
