I made this one when I was suffering from extensive neurological damage in my arm dueto a virus infection - my immune system was down pretty bad by the end of 2017.
So in order to still be able to make art, I used a lot of "concept art techniques" - e.g. some photobashing (photos were all taken by myself, and I was working with a model: xxmilkytea) , to compensate for the parts that I could not paint because of too much pain and shaking going on.
Tutorials that helped me out for the painting parts were from Ross Tran and Irakli Nadar. :)
Check the video below to see how it was done. :)
