This is some of the concept artwork that I did for the LEGO movie, "Bionicle: Mask of Light". The Rahkshi were the reptilian-like villains of the film. LEGO had already designed the toy but wanted some additional conceptual artwork that explored the Rahkshi's physiology. The "Krana" were the creatures that lived in and controlled the Rahkshi.
I had a lot of fun with this design. Note, some ideas that I came up with was deemed a bit "too scary" for some of the film's target audience, so a lot of the notes on the drawings are "NOT OFFICIAL". Consider the artwork presented here as a early brainstorming exercise rather than anything official.
