Slenderman is capable of oustrecthing his limps to unnatural lengths and it is said that when hís arms are fully outstretched you fall into some kind of hypnosis and can't resist walking into them..
And actually he's not a he... He's an it.. It's a sexless being

Though I prefer saying 'He'
In some versions he has a wide, toothy smile, in other versions he has a top hat..
There are so many versions of Slenderman I still have to fully explore...!
Oh and I tried a blue color scheme this time..! I promised someone that ;D
I love the coloring
