I enjoy the ideia, but think the arrows' bases shouldn't blur and mesh together. If there were a sharp and angled line between them it would favor the perception of depth.

Maybe if you add a background grind to the icons they could become more visually appealing!

Well, it's supposed to indicate rotation, but I see your point. I'll add some variations, and see if I can add a grid that looks decent.

Very simple arrow pack, hardly a freehand work with nearly effortless minimal execution, they are not horrible quality however and could be useful to some. Substandard material.
