Premise - Developed Sketches

I have worked on developing some different designs for a main character. I have spent some time looking into some Japanese folklore, and some ghost/ creature designs. Studio Ghibli really excels in the mixture of source material and personal style. While I am not working from an existing piece of source material, in terms of style I would like to take the best aspects of all my influences and mix them with my own style. Currently in my designs there is lots of contrast in colour to environment. I am not completely decided on the look that I want to create but after some more sketches the idea should hopefully be more clear.
