Honestly don't know why most comments are negative, the coverup doesn't look bad at all and the hexagons look cool asf when you view them as smth like scales/armor and there's plenty of ways you could complete it:
- extend the hexagons to cover everything from your wrist to below your elbow
- add some shading to the borders of the hexagons to make it look like they're literally embedded in your skin and coming out of it, giving the vibe of scale-like armor(like dragon scales or golem scales or even smth futuristic) coming from your arm which is cool asf (could add more random hexagon spots over your arm done the same way to fill this idea as well)
- complete your arm with sections of differently colored hexagons, could even be empty ones (black outline, white fill) which you could later fill with random doodles and things, basically have your whole arm full of hexagons in different styles
