First I thought it was pixelart, 'Cause I'm studying that a lot. When I ment 1x1 actually ment (1:1) (that means that 1 pixel is stretched as 1 pixel) (cause you can do 1x4 to make it look pixelated) When I ment AA, actually i thought you were a pixel artist, cause as a pixelartist you should know that it's really hard, because you cannot use algorithms you have to add it pixel by pixel...
Alright, so you aren't a pixel artist. That means you do the vectors and then scale them?
Most of the things on the pixel ponies are done on the pixel scale. But some thigns like cutie marks I scale down from vectors and then touch up on the pixel scale.
I don't really mess with Pixel Aspect Ratios so its all 1:1 stuff.
I consider myself a pixel artist. The scale down trick is actually the way a good amount of the art is actually made in 2d fighting games. For like Character portraits and the like. and all of the art in games like arcana heart.
