Grey doodle

Drew this during my wait in League of Legends... around midnight... damn I should not draw when I'm tired. The composition in this is kinda bad haha. But that doesn't matter cause I was trying to figure out blending. 

I was trying to figure out some blending techniques that so many artist have (That I extremely lack in)
Like 's and 's talent (Is talent even the right word?) inspires me sooo much when it comes to blending with a realism sort of touch.
