Grasper! Monster conception for Hell Express

Hi, Guys.
This design is a concept art I made for our first game, , a four-player co-op isometric shooter game. It appeared in the trailer, coming with an extremely nice scene. Click here if you haven't seen the video: https://www.youtube.com/watch?v=kEIHXp_F4VE
