Step by step process of this:
Some people asked me to make a tutorial for pixels, but I really don't have any plans for making one
(I think those who know me from before probably remember me saying that I fail at explaining with words, so I don't want to do one.)
Here's something similar (I guess) - I think it shows how I do pixels without having to explain each frames
Just in general, here's what I do in 5 steps:
2. Choose basic colors
5. Animate (if I must)
Other requirements: Lots of time + patience + guts to work + chocolates to keep your sanity.
