Slendy Fanart- What am I doing...

There's a storm where I live so I decided to doodle on Sai while I was waiting for my wifi to work. This took me like 5 minutes. Slenderman's pretty creepy. By the way, please ignore my fail collar xD I don't know why but I just couldn't draw one at the moment. I don't even know how many tentacle things he has so if there are too many or not enough please tell me so I can fix it. xD
