A: Some textures with different colors, (e.g. Terracota, TNT) when scaled to small size, can look not similar to their original size.
Q: After building in-game, part of my image is missing. Why?
A: This can caused by reaching height limit, including blocks, that are not in the current game version or spawning blocks out of your max render distance.
Q: There are too many pages in command block convert output!
A: You can reduce number of commands, if you optimize your image to include more simillar blocks.
