Patreon.com is a website where artists can create videos or text guides to help other people learn new skills from them. In return, if someone finds their work helpful they can choose to donate money to that individual.
One artist we've came across is Pedro Medeiros. He is a game artist, programmer and co-founder of games company MiniBoss. He's decided to dedicate his Patreon site to teaching others to make pixel art.
Here you will find lots of tutorials like this one on how to incorporate motion blur into your animations.
Pixel art is a popular trend for many games and animation at the moment so these guides may be helpful for students and professionals alike.
