There is only one angle for isometric pixel art, and that isn't it..
No, there are of course many possible angles. An isometric image is basically just a 3D image with no real depth.
How did I get the angle wrong?
Your top-view against front view ratio is 1:1, and in this thread we have been making the pieces 1:2. At your angle it looks kind of distorted and unnatural, but keep trying!
