Alright, third and last post about this artist, but I already found another awesome artist.
Here goes the credits :
This is a collection of drawings made by a girl called Josi, a 19 years old wannabe concept artist.
These pictures are from her tumblr blog : syntheticimagination.tumblr.com/
All credits to her.
