I enjoyed drawing this one, because I did something similar a few years ago here - Demon Woman With Wings
With this design I was thinking about a costume for her and to draw this completely from scratch, because the other one I had some help with a reference picture.
I used some promarkers and prismacolor pencils which I always buy from amazon.com or ebay.com as you can always find them cheaper than actual art shops such as hobbycraft.co.uk
Please let me know if you have a suggestion for me to draw, all suggestions are welcome and will be noted.
