The icons looks fine.
But I don’t like the white are around the icons it looks kinda of like a background also it has some strange black bits in the White section which I don’t like to.
You’ve included some icons 8 icons to be exact which make it a full icon set I’d of preferred to see the icons in more than just 256x256 icons size.
Anyway not to bad for a icon set just could do with a few improvements.
