Pixel murr

This is one of my old as shit charas 8D

His name was Murr... he was such a sweetie pie... so i decided to use him as a test subject for my pixel art :/

i like it... but dont LOVE it...

the hearts are maybe the best things and they took me a couple seconds... eh ...

if anyone has tips of pixel art or knows anything about it, please tell me ;w; i love to learn!!
