Edit these three icons

[MrHorror]

Hello. I need a few small edits done to three icons. They're attached below in this thread. For the grim reaper icon, I want the light-colored background behind him changed to a tree-bark-brown color. But I need this done without touching or messing the small black shreds hanging behind him in the icon.

For the Facebook icon, just need small bits of visible blood splatter added. For the Twitter icon just need small bits of blood splatter added. Also, if you can re-color the icon to the typical twitter light blue and white? But keep the grunge on it. I just want the grey and dark blue colors re-colored to light blue and white with grunge and blood splatter.
