My Three Rules
1 - Must be deformed/inhuman in some way, adding to the mystery of my character.
2 - The musical instrument my character uses must double up as a weapon in some form.
3 - Must be larger than the average human for the added fear aspect.
My Research
below I will showcase my moodboards and other such research that will eventually show my concept drawings following on from the research I did.
This moodboard shows my research into different horror characters/creatures and the different media they are portrayed in.
A majority of my research came from media that shows deformed, inhuman or unexplainable creatures. I chose this as a focus because the subject interests me and gives a lot of leniency when designing a character.
This is a moodboard for my research into the possible styles and instruments I could implement into my character. I like the idea of the phantom of the opera as it is a mysterious character with lots of leniency for deformation in it's design. I also like the idea of a harp for my character as it is an almost angelic, but haunting instrument that would be an interesting contrast with a deformed creature wielding it.
This is one of my earliest concepts in which I designed a creature mad almost entirely of hair. The monster has shadowed black skin and bright yellow beady eyes, the combination of it's stick like build, hair coated body and beady little eyes give this creature a sense of mystery.
Above is another one of my original concepts. This design is of a large spherical monster that overshadows some buildings, expressing it's sheer size. This monster wields a large shoddily made guitar that is crafted out of a building. I don't like this design due to it not fitting with my rules all that well.
Final Moodboards
This is a moodboard I created to show some of the classics and greats of the horror genre. A lot of these characters interest me for different reasons. Jeepers Creepers (bottom right in the hat) interests me, for example, due to his unexplained nature of appearance and the concept of him being able to pass as a human being. I find this interesting as it adds a twist to his movies as he can be feared both as a human and as Jeepers Creepers himself. I also like the design of the deadites from the Evil Dead (middle right) as the concept of an almost unkillable monster can be boring in video games but Sam Raimi brings it together incredibly well and keeps the audience interested and his monsters memorable.

I decided upon doing a moodboard on famous weapons as it helps to reference known weapons when doing my drawings. Leatherface's chainsaw particularly interests me because as it is such a simple weapon that managed to strike fear into the hearts of teenagers in the 80's with the combination of Leatherface's skin mask, famous character design and use of a common DIY object as a weapon.
