I love the giant "NOT YOURS, FUCKA!" In the middle of the drawing. Most watermarks are little and gentle white/grey transparent texts with the artist's name on them and nothing more... And here we have...
YA DONT FAKIN OWN THIS, YA LOO0O0O0OSER! AH-HAHAHAHA! THAT'S RIGHT, YA KNOW YA WANT IT... BUT YA DON'T HAVE IT! HO-HAH!
It is funny and awsome though, please don't change it.
Oh and yeah, of course they do look just as cute and awsome and really well drawn as ever, vemry floompfy and colours are picked out just right. But it is kinda obvious by now that you're awsome at art. Hell ye.
