Akuma sketch dump

:'D aah.. it feels like it's been while since I last submitted anything ;w;
but I feel guilty because I need to finish a certain drawing before submitting anything else 
(This doesn't count because.. they're sketches I've done way earlier than the drawing I need to do x'D) 

Anyway.. these drawings are from an story my friends and I have been planning for over more than 4 years already :'D I just need to draw  
(there's a page I copied from Girls of the Wild's up there, that's not mineee!! it was just a pose practice)
