I've been lurking and sketching out better designs for the characters that were made 2013-2015. Including those that I adopted as Acario is not an exception, he honestly one of favorite characters right now. Also I recalled the adopt seller not minding design tweaks as well when you buy something it is yours now. (See here https://www.deviantart.com/trix-master/art/Ref-Sheet-Acario-the-Potion-Mixer-558936569) That and it's been 5 years it's a miracle his old adopt sheet is still up (glad to see the adopt seller doing well, nice improvement in art)
He's still the magic cat that is stern, I just ramped up grumpiness on him. Based his form on more patchy spinxes and oriental long hair cats.
