Have done a couple of sketches of some sets for the Horror genre. The first was a very basic looking lab, with lots of shelves containing chemicals and books in all shapes and sizes. The second had much of the same elements of the first however I incorporated objects such as broken violins, pipes and stings in various places hanging down from the ceiling. I also added in a cog, which represents  Holmes' constant thoughts, analysing and examining everyone and everything.

I next drew a more final design. I used elements from the second image, changed the shape of the cog; adding a second one with the intention of the two rotating, symbolising thoughts. There is also a magnifying glass, which symbolises his almost over analytical lifestyle, also an object and symbol associated with the character. On the cogs, there is the shape of sound hole on the violin and the strings with the tuning pegs which come across the dips in the cog. Bullet holes litter the walls, and the 'VR' is marked into one of the cog's also. Little bottles of 7% solution of cocaine are piled together and a syringe with violin strings wrapped around the outside. Bookshelves with books, papers, chemicals (some which have fallen over and dripping onto the floor. Books and papers piled and discarded around the set. The table is full of chemicals, tubes and wires all twisted together eccentrically. Also there are four wires set evenly apart from each other; these represent the four strings on the violin. The floor is etched with symbols; mostly musical but also cyphers and question marks. 

Then I scanned the image into photoshop and played about with the colours, looking at how the colours effected the mood of the set. The colours didn't come out extensively as the original was a pencil drawing with every little shading.
