After watching the new Batman movie, I found a lot of fanart out there, and some were of the main villain, The Riddler, but as a woman. So I wanted to try something with this nerdy but scary villain
This was the original pencil sketch, I found cool to add it blood, so try it with a red market and it looked cool.
Then, I made the digital sketch, I use the software Paint Tools Sai. Took the chance to correct some proportions.
Finally, added the color and shadows. Here next, a version of the finished pic, but without the dead-looking eyes and blood stains.
