On the morning of sunday, July 30th, the second day of the GalaCon I made this drawing of Octavia to complete the series of characters as tributes to the guests of honor at the GalaCon. Chalk Octavia was for Kazumi Evans.  
I am happy with how she turned out, but there are two flaws. looking at her forehead there should either be a little gap under her mane or her mane would have to be a little lower. The main above and below her her are unfortunately not properly aligned. I’ll pay better attention to such significant details in the future. The yellow rim around her works nicely though to set her apart from the gray stone on which she is drawn.  
This is a color intensified version of the drawing.  
Here is a photo without intensified colors.  
I do hope that Kazumi Evans also got the origami figure of Octavia I made for her. Since I missed any chance to talk to her I asked one volunteer who would attend a signing session for the volunteers to pass the origami on to her.
