Looking for a pic

I randomly found this pic as somebody’s profile pic on fimfiction:  
 
I thought the art style was really cool and tried reverse searching it on google… but it turned up nothing. All I got was more people across the internets using this pic as an avatar, but no source (or even a full pic).
 
Help a brother out?

this might be an oc. or the somebody made it themselves.

Tried uploading to google images?
