This is almost like a blatant copy, but whatever. You decal was obviously hand drawn at a resolution 256x256. My decal was drawn at 4096x4096 in a vector SVG environment. Most decals made for blockland are mostly hand drawn at a low canvas size making them look absolutely hideous. Why don't you try to use vector skills to make your art look better? Not saying that your decal looks bad, but personally, in my opinion, it kinda looks meh.
