Sketchbook assignment for week 2 of year 4

These images are for my sketch book assignment for Tuesday September 24 ,2014. I had scanned in a few drawing and added colour and an outline in Photoshop. The Sketch book topic i chose was "In a series of pictures or three dimensional works, show subject undergoing a change over a period of time".
The story is of a character that finds some kind of strange helmet. The character puts the helmet on and becomes a wicked beast.
